The best broccoli seeds depend on whether you want sprouts and microgreens or full garden heads: those goals call for different seed quantities, varieties, and growing methods. My best overall pick is Purely Organic Waltham 29 for gardeners seeking an organic, open-pollinated planting variety. For frequent sprouting, Organo Republic’s 1-pound bag offers a larger supply, while Survival Garden Seeds’ five-variety mix suits growers who want to compare types. The main tradeoff is between planting-purpose seeds and sprouting-purpose seeds, with package size and variety shaping the next choice. Read on for how all 14 options compare and which fits your growing plans.

Key Takeaways
- Growing purpose matters more than the word broccoli. Several picks are aimed at sprouts or microgreens, while Waltham 29, Di Cicco, purple sprouting, and Romanesco options are geared toward garden growing.
- Waltham 29 is the roundup’s most common planting type. It appears across several listings, so compare certification, seed count, and package details rather than assuming the variety name alone makes products interchangeable.
- Bulk bags favor repeat sprouters. The 1-pound Rainbow Heirloom Seed Co. and Organo Republic packs provide more seed for ongoing batches, but need suitable storage and regular use.
- Specialty varieties offer a different harvest, not a universal upgrade. Purple sprouting, Romanesco, and Di Cicco give gardeners alternatives to standard Waltham 29, but may be less suitable for buyers seeking a familiar green broccoli head.
- Organic labels and seed counts vary across the lineup. Buyers should match verified product claims and stated quantities to their needs instead of treating heirloom, non-GMO, and organic as identical standards.

More Details on Our Top Picks
Broccoli Seeds for Sprouting & Microgreens | Waltham 29 Variety | Non-GMO & Heirloom Seeds | 1 LB Resealable Bag | Rainbow Heirloom Seed Co.
For households that sprout broccoli regularly, Rainbow Heirloom Seed Co.’s one-pound bag offers much more seed than the 4-ounce NOW Foods option, reducing how often you need to restock. Its Waltham 29 heirloom seed is described as suitable for both sprouts and microgreens, giving growers flexibility to use a jar or a tray. The product also lists U.S. origin and non-GMO status, useful details for buyers prioritizing provenance. The tradeoff is purpose: this is a sprouting-and-microgreens pick, not the better fit for someone seeking full garden heads like the Di Cicco planting seeds. A large bag also calls for dependable storage and a regular sprouting routine; it may be more seed than an occasional user can use conveniently.
Pros:- One-pound package suits repeat sprouting and microgreen batches.
- Waltham 29 variety is identified for both sprouts and microgreens.
- Listed as non-GMO and heirloom.
- U.S. country of origin is specified.
Cons:- Not presented as a seed for growing mature garden broccoli heads.
- The large package may be inconvenient for occasional sprouters or limited storage.
- Sprouting or microgreen growing still requires a suitable jar, tray, or setup.
Best for: Frequent home sprouters and microgreen growers who want a larger supply of Waltham 29 seed for jar or tray growing.
Not ideal for: Gardeners whose main goal is harvesting mature broccoli heads, or occasional sprouters who would prefer a smaller package.
- Variety:Waltham 29
- Package weight:16 oz (1 lb)
- GMO status:Non-GMO
- Seed type:Heirloom
- Country of origin:USA
- Brand:Rainbow Heirloom Seed Co.
Our verdict“Choose this bulk Waltham 29 option if you sprout or grow microgreens often; choose Di Cicco seeds instead for full-sized garden harvests.”
NOW Foods Broccoli Seeds for Sprouting, Non-GMO Project Verified, 4 Ounces
NOW Foods’ 4-ounce package is the most approachable choice here for someone trying home broccoli sprouts before committing to bulk quantities. Its listed serving guide says one tablespoon, about 10 grams, yields roughly 84 grams of sprouts, which helps a new sprouter plan a batch. The Non-GMO Project Verified status is a distinct credential, while Rainbow Heirloom Seed Co.’s one-pound bag is better suited to frequent use and the 8-ounce organic sprout seeds offer a larger middle ground. This smaller format limits leftover seed, but it also means replenishing sooner if sprouts become a regular food. Growing takes soaking and several days of sprouting, and the product is intended for sprouts rather than mature broccoli plants.
Pros:- Smaller 4-ounce package is suited to trying home sprouting.
- Non-GMO Project Verified status is specified.
- Serving information includes an approximate sprout yield.
- Product is described for straightforward home sprouting.
Cons:- The package is smaller than the 8-ounce and 1-pound sprouting options in this group.
- Sprouts require soaking and about 3–5 days of growing time.
- A sprouting jar or similar equipment may be needed.
Best for: First-time or occasional sprouters who want a modest package and a stated seed-to-sprout yield for planning small batches.
Not ideal for: Frequent sprouters who want a larger supply, or gardeners looking for seeds to raise full broccoli plants.
- Package weight:4 oz
- GMO status:Non-GMO Project Verified
- Serving size:1 Tbsp (about 10 g)
- Approximate yield:About 84 g of sprouts per serving
- Intended use:Sprouting
- Brand:NOW Foods
Our verdict“Pick NOW Foods for modest, planned sprout batches; choose Rainbow Heirloom Seed Co. if you already sprout often and need bulk quantity.”
1350+ Organic Broccoli Seeds for Planting – Heirloom Non-GMO, Di Cicco Variety
Di Cicco’s side-shoot production gives this planting seed a different payoff from the sprouting-focused NOW Foods and Rainbow Heirloom options: it is meant to grow into broccoli plants, with repeated smaller harvests after the main head. Its listed 48–70 day maturity range and planting zones 3–10 help gardeners judge whether it fits their season, while the package count of more than 1,350 seeds can support a substantial planting plan. Organic, non-GMO, and open-pollinated attributes also distinguish it among the garden choices. That breadth asks more of the grower, though: consistent moisture and attention to timing matter, and a large count is unnecessary for someone with only a few containers. Buyers seeking sprouts rather than garden crops should choose a sprouting seed instead.
Pros:- More than 1,350 seeds support a larger garden planting.
- Di Cicco is described as producing abundant side shoots for continued picking.
- Listed for planting zones 3–10 and a 48–70 day maturity window.
- Organic, non-GMO, and open-pollinated attributes are specified.
Cons:- Successful head development calls for consistent moisture and attention to planting conditions.
- The large seed count may exceed the needs of a small garden.
- Not intended for sprouting or microgreen production.
Best for: Home gardeners with space for multiple plants who want cool-season broccoli and continued side-shoot harvests.
Not ideal for: Indoor sprouters, gardeners with only a small container space, or beginners who want a low-maintenance crop with little timing management.
- Variety:Di Cicco
- Seed count:1,350+
- Organic:Yes
- GMO status:Non-GMO
- Pollination type:Open-pollinated
- Planting zones:3–10
- Days to maturity:48–70 days
- Planting depth:¼–½ inch
- Sunlight:Full sun
Our verdict“Choose Di Cicco for a sizable outdoor planting and follow-on side shoots; choose a sprouting product if you want edible sprouts in days rather than garden heads.”
Purely Organic Broccoli Seeds (Waltham 29) – Approx 750 Seeds – USDA Organic, Non-GMO, Open Pollinated, Heirloom, USA Origin
For gardeners who want a named broccoli variety with a clear organic credential, Purely Organic’s Waltham 29 is the most specifically documented garden option in this set: it lists USDA Organic certification, open-pollinated and heirloom seed, U.S. origin, and an approximate count of 750. That makes it easier to compare with the Di Cicco seeds, which offer a larger count and a stated maturity range but a different variety. Waltham 29 is a garden seed, unlike NOW Foods’ sprouting seed, so it suits buyers planning outdoor plants rather than countertop batches. Its tradeoff is the smaller quantity and narrower planting-period information: the listing gives spring, but not a days-to-maturity estimate. It also needs garden space, well-drained soil, and regular care.
Pros:- USDA Organic certification is specified.
- Waltham 29 is identified as heirloom and open-pollinated.
- Approximate count of 750 seeds offers a defined planting quantity.
- U.S. origin and outdoor growing details are listed.
Cons:- The approximate 750-seed count is lower than the Di Cicco package’s 1,350+ seeds.
- The provided specs do not list days to maturity.
- Designed for outdoor gardening rather than indoor sprouting.
Best for: Gardeners who prioritize USDA Organic certification and want a moderate quantity of Waltham 29 seed for outdoor spring planting.
Not ideal for: Sprout and microgreen growers, or gardeners who need a large seed count or a listed days-to-maturity estimate to plan a tight season.
- Variety:Waltham 29
- Approximate seed count:750
- Organic certification:USDA Organic
- GMO status:Non-GMO
- Seed type:Heirloom
- Pollination type:Open-pollinated
- Country of origin:USA
- Planting period:Spring
- Soil type:Well-drained
Our verdict“Choose this packet for certified-organic Waltham 29 garden planting; pick Di Cicco if a larger seed count and stated maturity window matter more.”
Organic Broccoli Sprout Seeds (8 oz) – Non-GMO, Heirloom Seeds for Sprouting and Microgreens
This 8-ounce organic sprouting pack sits between NOW Foods’ 4-ounce starter quantity and Rainbow Heirloom Seed Co.’s one-pound bulk bag, making it a practical middle option for regular but not heavy sprouting. It is described as organic, non-GMO, and heirloom, with U.S. origin, and the listing states that germination is guaranteed. Those details make it more suitable for buyers who prioritize growing credentials and want reassurance about seed viability than the basic serving-and-yield details provided by NOW Foods. The tradeoff is that the listing does not name a variety or give a specific germination percentage, so buyers cannot compare those particulars directly. Like the other sprouting choices, it is not for growing mature garden heads, and the seeds need proper storage to maintain quality.
Pros:- Eight-ounce quantity falls between the 4-ounce NOW Foods pack and 1-pound Rainbow Heirloom bag.
- Listed as organic, non-GMO, and heirloom.
- U.S. country of origin is specified.
- Germination is stated as guaranteed.
Cons:- The product data does not identify a broccoli variety.
- No specific germination percentage or seed count is provided.
- Limited to sprouting and microgreen use rather than mature garden crops.
Best for: Regular home sprouters who want an organic, U.S.-origin seed in a package larger than a starter size but smaller than a one-pound bulk bag.
Not ideal for: Gardeners seeking a named variety for outdoor broccoli heads, or buyers who need a stated seed count or precise germination percentage.
- Package weight:8 oz
- Intended use:Sprouting and microgreens
- Organic:Yes
- GMO status:Non-GMO
- Seed type:Heirloom
- Germination:Guaranteed
- Country of origin:USA
Our verdict“Choose this pack for a mid-size organic sprouting supply; pick NOW Foods for a smaller trial pack or Di Cicco for outdoor broccoli plants.”
Organo Republic Broccoli Sprouting & Microgreens Seeds – Non-GMO, Heirloom, 1lb Resealable Bag for Soil, Coconut Coir, Hydroponic & Aerogarden Growing
Organo Republic is the most adaptable microgreens pick here: its broccoli seeds can be grown in soil, coconut coir, hydroponic setups, or an Aerogarden, while the 1-pound resealable bag supports repeated batches. The listing estimates enough seed for up to 30 trays, a better fit for regular harvests than Nature Jim’s 8-ounce sprouting pack. Growing guides also give beginners a starting point, though results still depend on storage and consistent moisture. The tradeoff is purpose: these seeds are for broccoli microgreens, not full-size heads. If you want an outdoor crop, Waltham 29 options such as the 250-seed planting pack are more appropriate. Choose this when growing flexibility and supply matter more than mature broccoli production.
Pros:- Compatible with several growing media and systems, including hydroponics and Aerogarden
- One-pound resealable bag supports repeated microgreens batches
- Non-GMO heirloom seed with a stated high germination rate
- Includes growing guides for newer growers
Cons:- Intended for microgreens rather than mature broccoli harvests
- Regular watering and suitable growing conditions are needed
- Seed performance depends on proper storage and handling
Best for: Indoor growers who want to produce broccoli microgreens in batches across soil, coir, hydroponic, or Aerogarden systems.
Not ideal for: Gardeners seeking mature broccoli heads or buyers who only need a small quantity for occasional sprouting.
- Weight:1 lb
- Seed type:Broccoli microgreens
- Seed traits:Non-GMO, heirloom
- Package:Resealable bag
- Growing systems:Soil, coconut coir, hydroponic, Aerogarden
- Estimated tray capacity:Up to 30 trays
- Plant height:Up to 3 inches
- Growing schedule:Year-round
Our verdict“Pick Organo Republic for flexible, repeat microgreens growing, but choose a Waltham 29 planting variety if you want full-size broccoli.”
Nature Jim’s Sprout Organic Broccoli Seeds – Non-GMO, Sprouting Seeds – 8oz
Nature Jim’s is the straightforward choice for quick broccoli sprouts, with the listing describing a roughly five-day growing time and an 8-ounce pack suited to home batches. Its certified-organic and non-GMO status distinguishes it from the larger Organo Republic microgreens bag, which is better suited to repeated tray growing and multiple systems. This smaller pack makes more sense when you want sprouts for regular meals without committing to a pound of seed. The main limitation is that the product details focus on sprouting rather than mature broccoli plants, and they provide little guidance on specific growing setups or yield. Compared with the Sow Right Early Purple Sprouting broccoli, this is a fast indoor food crop, not a garden plant producing florets over a growing season.
Pros:- Described as producing sprouts in about five days
- Certified organic and non-GMO
- Eight-ounce pack is manageable for home sprouting
- Suitable for indoor or outdoor use according to the listing
Cons:- Smaller supply than Organo Republic’s one-pound microgreens pack
- Product details offer limited information about growing methods and expected yield
- Designed for sprouts, not mature broccoli heads
Best for: People who want a modest supply of certified-organic broccoli seeds for quick batches of home sprouts.
Not ideal for: Outdoor gardeners seeking mature broccoli plants, or frequent growers who would benefit from a larger seed supply and detailed setup information.
- Weight:8 oz
- Seed use:Sprouting
- Organic status:Certified organic
- GMO status:Non-GMO
- Stated growing time:About 5 days
- Package count:1
Our verdict“Choose Nature Jim’s for quick, small-batch organic sprouts; choose a garden variety such as Sow Right Early Purple Sprouting broccoli for outdoor florets.”
250 Broccoli Seeds for Planting – Heirloom, Waltham 29
This 250-seed Waltham 29 pack suits gardeners who want a manageable outdoor planting rather than a bulk supply. The variety is described as producing tight blue-green heads and side shoots for spring or fall harvests, and the included growing guidance can help with basic planning. Compared with the SVI 1000 Waltham 29 pack, this is the less excessive choice for a smaller plot or a first round of planting; the SVI pack offers more seed for successive sowings. The tradeoff is that yield depends on growing conditions, spacing, and care, so the count alone does not promise a particular harvest. Seeds are listed as viable for three to five years under proper storage, but this remains a full-size garden crop—not a quick sprouting option like Nature Jim’s.
Pros:- Waltham 29 is suited to cool-season spring and fall gardens
- Produces heads and side shoots according to the listing
- Non-GMO heirloom seed grown in the USA
- Growing guidance is included
Cons:- Smaller seed count than the SVI 1000-seed Waltham 29 pack
- Harvest quantity depends on conditions, spacing, and care
- Requires outdoor garden space and seasonal planning
Best for: Home gardeners with a small outdoor bed who want a limited quantity of Waltham 29 for spring and fall planting.
Not ideal for: Gardeners planning many successive sowings or buyers looking for seeds specifically intended for sprouts or microgreens.
- Seed count:250
- Variety:Waltham 29
- Seed type:Heirloom
- GMO status:Non-GMO
- Growing location:USA-grown
- Planting season:Spring and fall
- Storage viability:3–5 years under proper storage
Our verdict“Choose this pack for a modest Waltham 29 garden planting, but select SVI’s larger pack if you expect to sow repeatedly.”
Sow Right Seeds – Early Purple Sprouting Broccoli Seed for Planting Garden
Sow Right’s Early Purple Sprouting broccoli offers a different garden result from the green Waltham 29 packs: it produces tender purple florets and is described as cold tolerant, making it a distinctive option for spring or fall planting. The listed 60–70 days to maturity and 7–10-day germination window give gardeners a clearer schedule than the 250-seed Waltham 29 listing, which does not specify either interval. At 225 seeds, it is a moderate packet rather than the bulk choice offered by SVI’s 1,000-seed pack. That smaller count may suit a household plot, but it is less convenient for repeated sowings across a large garden. Plants reach 2–3 feet and need regular watering, so this is not a compact sprout-seed substitute.
Pros:- Purple florets provide an alternative to green Waltham 29 broccoli
- Cold tolerant and listed for spring or fall planting
- Includes germination and maturity timing
- Suitable for USDA zones 3–10
Cons:- 225 seeds provide less capacity than SVI’s 1,000-seed pack
- Plants can reach 2–3 feet and need garden space
- Regular watering and suitable soil conditions are required
Best for: Gardeners who want a cold-tolerant outdoor broccoli variety with purple florets and a stated maturity window.
Not ideal for: Growers who need a high-volume seed supply, compact indoor crops, or conventional green broccoli heads.
- Seed count:225
- Variety:Early Purple Sprouting broccoli
- Botanical type:Brassica oleracea
- Germination time:7–10 days
- Days to maturity:60–70 days
- Plant height:2–3 feet
- USDA zones:3–10
- Seed traits:Non-GMO, heirloom
Our verdict“Pick this for a home garden with room for purple, cold-tolerant florets; choose a Waltham 29 pack for traditional green heads or a larger seed count.”
SVI 1000 Waltham Broccoli Seeds (Brassica oleracea) – Waltham 29 Broccoli Seed Packets, Brassica Seed – Cool Season Heirloom Vegetable Seeds for Outdoors, Vegetable Garden
SVI’s 1,000-seed Waltham 29 pack is the clear choice for gardeners planning multiple sowings or planting a larger vegetable bed. It shares the cool-season focus of the 250-seed Waltham 29 option, but offers four times the listed quantity and a stated 3–10-day germination window. Waltham 29 is described as producing medium-green heads and abundant side shoots, which can extend the harvest rather than ending with a single central head. The tradeoff is scale: a large quantity is less useful for a small garden, and the product calls for full sun and regular watering. Growth may also be uneven, so the stated timing should not be treated as a guaranteed schedule. Unlike the microgreens products, this is meant for outdoor, full-size broccoli.
Pros:- 1,000 seeds support larger plantings and successive sowings
- Waltham 29 is suited to cool-season gardening
- Side shoots can extend the harvest period
- Germination is listed at 3–10 days
Cons:- Large seed quantity may exceed the needs of a small garden
- Requires full sun and regular watering
- Growth and maturity may be non-uniform
Best for: Gardeners with larger beds or those who want enough Waltham 29 seed for repeat spring-to-fall sowings.
Not ideal for: Small-space growers who need only a few plants, or anyone seeking quick indoor sprouts rather than outdoor broccoli.
- Seed count:1,000
- Variety:Waltham 29
- Botanical type:Brassica oleracea
- Germination time:3–10 days
- Plant height:20 inches
- Planting depth:1/4 inch
- Growing season:Spring to fall
- USDA zones:3–12
- Seed traits:GMO-free, heirloom
Our verdict“Choose SVI for a larger Waltham 29 planting and repeat sowings, but opt for the 250-seed pack if your garden is modest.”
Sow Right Seeds Broccoli Microgreen Seeds for Growing Microgreens
For the quickest harvest in this group, this packet is aimed at microgreens, not mature broccoli heads: the tender greens are ready in 8 to 12 days and have a mild, cabbage-like flavor for salads and sandwiches. Compared with Waltham 29 Broccoli Seeds, which need 50 to 60 days to mature, this is a much faster route to fresh broccoli greens—but it does not replace a garden crop. Its about 380 seeds and low-care, no-fertilizer approach suit small indoor batches, while the included instructions help newer growers get started. The tradeoff is limited scale and purpose: choose Waltham 29 or the five-variety Survival Garden Seeds set if you want full-size plants, larger harvests, or a range of broccoli types.
Pros:- Microgreens can be harvested in 8 to 12 days.
- About 380 seeds suit a small indoor growing setup.
- Non-GMO heirloom seed with no fertilizer required.
- Included instructions make it approachable for beginners.
Cons:- Designed for microgreens rather than full-size broccoli plants.
- The packet may not cover extensive or repeated sowings.
- Full-shade listing may not suit growers expecting a conventional sunny garden crop.
Best for: Apartment growers and first-time microgreen gardeners who want small, fast harvests for salads or sandwiches.
Not ideal for: Gardeners seeking mature broccoli heads, substantial outdoor harvests, or enough seed for repeated large trays.
- Seed quantity:14 g (about 380 seeds)
- Seed type:Non-GMO heirloom
- Germination time:8–12 days to harvest
- Growing location:Indoor or outdoor
- Light listed:Full shade
- Soil listed:Sandy soil
- Moisture:Regular watering
Our verdict“Choose this packet for quick, small-scale broccoli microgreens, not for mature heads or a large garden harvest.”
Waltham 29 Broccoli Seeds – Non-GMO Heirloom for Vegetable Gardens
Waltham 29 is the straightforward pick for full-size broccoli: it is listed for large blue-green heads and side shoots, with maturity in about 50 to 60 days. That makes it a better fit for a spring or fall vegetable bed than Sow Right Seeds Broccoli Microgreen Seeds, which are intended for fast, tender greens rather than heads. Its listed 20–24-inch height and 12–16-inch spread give gardeners a useful sense of the space required, and the stated USDA zones 3–10 cover a broad range. Cold and drought tolerance are appealing traits, though they do not remove the need for regular watering or full sun. Choose this single variety for a familiar garden crop; the Survival Garden Seeds five-variety collection offers more diversity but less of a one-variety focus.
Pros:- Produces large blue-green heads and side shoots.
- Matures in about 50 to 60 days.
- Listed for USDA zones 3–10 and described as cold and drought tolerant.
- About 200 seeds provide a defined quantity for garden planning.
Cons:- Requires full sun and regular watering.
- Spring and fall planting windows limit its fit for warm-season schedules.
- A single variety offers less crop diversity than the five-variety Survival Garden Seeds collection.
Best for: Home gardeners who want a familiar, single-variety broccoli crop with the potential for main heads and side shoots.
Not ideal for: Indoor growers, microgreen seekers, or gardeners without a sunny outdoor bed and room for mature plants.
- Seed count:About 200 seeds
- Seed type:Non-GMO heirloom
- Germination time:7–14 days
- Maturity:50–60 days
- Plant height:20–24 inches
- Plant spread:12–16 inches
- USDA zones:3–10
- Sunlight and water:Full sun; regular watering
Our verdict“Pick Waltham 29 for a conventional outdoor broccoli crop with side-shoot potential, provided you can offer sun and regular water.”
Broccoli Seeds for Planting – 5 Varieties – Survival Garden Seeds
Five broccoli varieties make this the diversity pick, spanning early shoots, green crowns, purple shoots, and Romanesco spirals. Compared with the single-variety Waltham 29 packet, this collection gives a gardener more forms and harvest possibilities across spring and fall planting. That range can add interest to fresh meals and gives growers options for freezing, but it also asks for more planning: the varieties may not share identical growing preferences, and the listing calls for full sun, loam, and regular watering. At a listed height of about 24 inches and zones 3–9, it is intended for an outdoor cool-season garden rather than indoor sprouting. The product data does not state seed count or individual variety names, so buyers who need precise sowing quantities or a specific cultivar may prefer a single-variety packet.
Pros:- Includes five broccoli varieties with green, purple, and Romanesco forms.
- Supports spring and fall planting in cool-season gardens.
- Untreated, heirloom, GMO-free seed according to the product data.
- Variety range suits fresh eating and freezing.
Cons:- Requires outdoor space, full sun, and regular watering.
- Different varieties may call for different growing conditions.
- The listing does not specify seed count or name each variety.
Best for: Outdoor gardeners who want several broccoli colors and forms to compare, serve fresh, or preserve from spring and fall plantings.
Not ideal for: Small-space growers, indoor microgreen growers, and buyers who need a stated seed count or a named single variety.
- Number of varieties:5
- Seed type:Untreated, heirloom, GMO-free
- Planting period:Spring and fall
- Expected plant height:About 24 inches
- Soil:Loam
- Moisture:Regular watering
- USDA zone:3–9
- Sunlight:Full sun
- Expected harvest:Spring to fall
Our verdict“Choose this collection if garden diversity matters more than a precisely quantified packet or one specific broccoli variety.”
Romanesco Broccoli Seeds – Sow Right Seeds
Romanesco is the distinctive choice for unusual heads, with a fractal shape and mild, nutty flavor that sets it apart from the conventional blue-green Waltham 29. This is still a full-size outdoor crop, not a quick microgreen option like Sow Right Seeds Broccoli Microgreen Seeds: expect 75 to 85 days to maturity and plants reaching 24–36 inches tall. The packet lists 275 seeds, a useful quantity for gardeners who want room to sow more than a handful, and gives clear planting depth and spacing. Its zones 3–10 range is broad, but full sun, regular watering, and a longer wait narrow the best fit. Choose it for culinary variety and visual impact; skip it if speed or familiar broccoli heads matter more.
Pros:- Produces distinctive fractal-shaped heads with a mild, nutty flavor.
- Packet contains 275 seeds.
- Listed for USDA zones 3–10.
- Planting depth and spacing are specified.
Cons:- Takes 75–85 days to mature, longer than Waltham 29.
- Requires full sun and regular watering.
- Plants can reach 36 inches tall and need substantial spacing.
Best for: Gardeners with a sunny outdoor bed who want an unusual, nutty-flavored broccoli for cooking and serving.
Not ideal for: Growers seeking quick harvests, compact plants, or conventional broccoli heads within a shorter season.
- Seed type:Heirloom, non-GMO
- Seeds per packet:275 seeds (750 mg)
- Planting depth:1/4 inch
- Spacing:24 inches apart
- Plant height:24–36 inches
- Plant spread:16–18 inches
- Germination time:8–10 days
- Maturity:75–85 days
- USDA zones:3–10
Our verdict“Choose Romanesco for a longer-season garden crop with unusual looks and flavor, rather than for quick or compact broccoli growing.”
How We Picked
I grouped the 14 listings by their stated use: garden planting, sprouting, microgreens, or specialty varieties. I weighed how clearly each product identifies its variety and intended growing method, then compared the practical implications of seed quantity, certifications, and package format. A large sprouting bag can make sense for regular batches but is less useful to someone planting a few garden rows; a small planting packet may be easier to manage but offers less seed for repeated sowing.
The ranking favors options with a clear fit and useful differentiation, rather than treating every broccoli seed as interchangeable. Purely Organic Waltham 29 leads as a clearly specified garden choice, while Organo Republic and Rainbow Heirloom Seed Co. rise for bulk sprouting use. Specialty garden seeds and mixed-variety packs rank well for narrower goals, but below the more direct choices for buyers seeking a straightforward planting or sprouting match. Product claims are compared as listed; certifications and intended uses should be checked on the package before sowing or eating.

Factors to Consider When Choosing Best Broccoli Seeds
Before choosing a packet, decide what you want to harvest and how often you plan to grow. The right seed for a tray of sprouts may not be the right choice for garden heads, and a specialty variety can change the harvest more than its label suggests. These factors help narrow the field beyond the individual product differences.
Choose Between Garden Heads, Sprouts, and Microgreens
Start with the harvest, not the seed count. Sprouting seeds are selected and packaged for repeated small batches, while garden varieties are intended to grow into mature plants; microgreens are harvested young and may be grown in trays or other setups. A listing that mentions both sprouts and microgreens does not automatically mean it is the best fit for planting outdoor broccoli heads. Check the stated purpose and follow food-safety directions for seeds meant to be eaten raw or lightly cooked. Buying for the wrong harvest can leave you with a large supply that does not match your routine.
Read Variety Names as Growing Choices
Waltham 29 is the most frequently listed garden type in this group, while Di Cicco, purple sprouting, and Romanesco offer distinct alternatives. Variety affects the shape and type of harvest, so choose based on what you want on your plate and what suits your growing season. A specialty name is not a guarantee of easier growing or greater yield. If this is your first planting, a familiar standard variety may make results easier to interpret than an unusual type. If you already grow broccoli successfully, experimenting with one specialty packet alongside a dependable variety limits the risk of an all-or-nothing crop.
Match Package Size to Your Growing Rhythm
Bulk packs can be practical for people who sprout seeds often or sow several trays, but they create a storage obligation. A smaller packet may better suit a first garden bed or a one-time trial, even if it leaves less room for repeat sowing. Seed quality can decline when packets sit through heat, moisture, or long storage, so keep unopened seed cool, dry, and sealed according to package guidance. Avoid buying a large bag solely because the quantity looks convenient. Estimate how many batches or planting rows you will actually use before choosing between a small packet and a pound-sized supply.
Separate Organic, Heirloom, and Non-GMO Claims
These labels describe different attributes and should not be treated as synonyms. Organic certification refers to production standards, heirloom describes a variety or seed-saving history, and non-GMO is a separate claim about genetic modification. Some listings state several of these claims, while others emphasize only one. If certification matters to your purchase, check for the specific certifier or wording on the current package rather than relying on a broad product title. Buyers who mainly need a particular growing type may give variety and intended use higher priority than labels that do not answer those questions.
Consider Your Climate and Planting Calendar
Broccoli is a cool-season crop, but the right sowing window depends on local temperatures, frost dates, and whether you are growing for a spring or fall harvest. A seed packet cannot compensate for planting during heat that stresses young plants or shortens the useful harvest window. Check the variety’s instructions and compare them with your local extension service or regional planting calendar. Gardeners in short seasons may value timing guidance more than a large seed count. Those growing sprouts indoors face a different timing question: whether they can maintain a clean, repeatable routine throughout the year.
Plan for Storage and Food-Safety Habits
Seed intended for sprouting needs more than a jar and water: clean equipment, careful rinsing, and prompt refrigeration after harvest all matter. Raw sprouts can carry food-safety risks, so follow reputable handling guidance, especially when serving people at higher risk from foodborne illness. For garden seed, the main concern is preserving viability between seasons by limiting moisture, heat, and light. Do not assume that a resealable bag alone protects seed indefinitely once opened. Choose a package size you can store well and use within a sensible period.
Frequently Asked Questions
Can I use garden broccoli seeds to grow sprouts?
Do not assume a garden seed is intended or processed for sprouting just because it is broccoli. Check that the package specifically identifies sprouting or microgreen use and follow its food-safety directions. Garden packets may be sold for planting rather than eating as sprouts, and their handling details can differ. If sprouts are your goal, the sprouting-focused listings in this roundup are the more direct match. Keep clean tools and use safe storage practices with every batch.
Which should I choose: Waltham 29 or a specialty variety?
Choose Waltham 29 if you want a familiar garden broccoli type and a straightforward starting point among the planting options here. Di Cicco, purple sprouting, and Romanesco are better choices when you specifically want a different form or harvest style. Specialty varieties do not automatically grow better in every region, so check their growing instructions against your climate and season. If you are unsure, planting a standard variety alongside one specialty type gives you a comparison without relying on a single crop. The best fit depends on the harvest you want, not the variety name alone.
Is a one-pound bag a good choice for a first-time sprout grower?
A one-pound bag is usually more seed than a beginner needs for a few trial batches. Larger packs make more sense if you already know you enjoy sprouts or plan to grow them regularly. A smaller option lets you learn your preferred batch size and routine before committing to a bulk supply. If you do choose a large bag, plan a cool, dry storage spot and keep it sealed between uses. The lower-waste choice is the amount you can use while maintaining good storage habits.
Does an organic label mean broccoli seeds are safe to eat as sprouts?
No. Organic describes production standards; it does not by itself confirm that seed is intended for sprouting or remove food-safety risks. Look for an explicit sprouting-use statement and follow the product’s handling instructions. Even seeds sold for sprouting need clean equipment and careful storage, since raw sprouts can support harmful bacteria. People at higher risk from foodborne illness may want to avoid raw sprouts or follow health-agency guidance. Treat intended use and safe handling as separate checks from certification.
Should I buy a multi-variety pack or one broccoli variety?
A multi-variety pack suits gardeners who want to compare different types and are willing to track which variety grows best in their conditions. A single-variety packet is simpler when you want a predictable crop or plan to save notes for next season. Check how many seeds are included for each variety; a pack with several types may provide fewer of each than a dedicated packet. For a first garden, one familiar variety plus a small specialty trial can be easier to evaluate than several new varieties at once. Choose variety breadth only if you have room and time to grow and record the differences.
Conclusion
For most gardeners seeking a clearly specified planting option, my best overall pick is Purely Organic Waltham 29. Best value for repeat sprouting goes to Organo Republic’s 1-pound bag, while Rainbow Heirloom Seed Co. is another bulk choice for buyers who want Waltham 29 labeled for sprouts and microgreens. For a best premium-style choice based on stated organic and variety details, Purely Organic Waltham 29 is the strongest fit; buyers who define premium by quantity should compare the bulk sprouting packs instead. Beginners should start with a smaller, clearly labeled packet matched to their goal rather than buying in bulk. For specific needs, choose the five-variety Survival Garden Seeds pack for variety testing, Sow Right’s purple sprouting or Romanesco seeds for a distinct garden crop, and sprouting-focused options when growing edible shoots is the plan. The best choice is the one whose purpose, quantity, and variety match the harvest you will actually grow.
