A 500-pound county-fair pumpkin starts with the right seed, not just any seed. Giant pumpkin varieties like Dill’s Atlantic Giant or Big Max are a completely different animal from the carving pumpkins at the supermarket. They demand space, patience, and the right genetics to push past 100 pounds and into record territory. This guide evaluates top giant pumpkin seed packs on Amazon by germination rates, seed counts, and verified grower results.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The right seed pack separates a casual grow from a competition contender. Here is everything you need to know to pick the best giant pumpkin seeds for your garden and your goals.
Our Picks at a Glance
How To Choose The Best Giant Pumpkin Seeds
Not every “giant” seed has the genetics to yield a 100-pound pumpkin. Some are standard jack-o’-lantern types with optimistic labels.
Genetics vs. Marketing
The world-record pumpkin lineage (over 2,700 pounds) traces back to Dill’s Atlantic Giant. For competition, look for “Dill’s Atlantic Giant” in the description, not a generic “giant” claim.
Seed Count and Germination Rate
A small seed count pack can start to look expensive if only a few sprout. Higher seed counts give you a buffer against poor germination, soil issues, or pests. Look for packs with at least 10 seeds for a solid chance at several healthy vines.
Space Requirements
Giant pumpkin vines are aggressive. A single Atlantic Giant plant can spread 15 to 20 feet in all directions. If you only have a small raised bed, a collection of smaller decorative varieties might be a better fit.

In‑Depth Reviews
1. Heirloom Pumpkin Seeds for Planting (CZ Grain)
Our pick — over 4★ from 20+ verified ratings; the strongest balance of quality and price.
A 10-pack sampler of heirloom giants that lets you find your favorite before committing to a single variety.
This collection from CZ Grain gives you 10 seeds across a mix that includes Atlantic Giant, Blue Jarrahdale, Porcelain Doll, and other rare varieties. The idea is smart — instead of betting an entire season on one type, you get a tasting menu of shapes, colors, and sizes. The brand promises a high germination rate, and the reviews back that up with multiple reports of all four seeds sprouting in under a week.
The catch is the seed count. You get 10 seeds here versus 5 packs in the competition pack, but half the seeds are decorative, not record-chasing giants. One review mentions that half the seeds did not come up, which is a reminder that heirloom mixes can have variable germination. The expected plant height is only 24 inches, so the “giant” varieties in this mix may be on the smaller end of the spectrum.
The standout feature is the color range. You get greens, blues, whites, pinks, and warty textures. This makes it the best pick for someone who wants a diverse autumn display rather than a single 500-pound behemoth. The USDA hardiness zone range (3-10) means it works in nearly every American garden.
Variety Score
- 10 different heirloom types in one pack
- Includes Atlantic Giant genetics for size
- Helpful video guide for beginners
The Trade-Off
- Mixed germination reported by some buyers
- Half the seeds are decorative, not true giants
- Only 10 seeds total for
Reach for this if: you want a low-risk way to experiment with several heirloom giant and ornamental varieties in one season.
Look elsewhere if: your only goal is a single massive competition pumpkin — you want a full pack of Atlantic Giant genetics.
2. Atlantic Giant Pumpkin Seeds (Survival Garden Seeds)
A straight-to-the-point Atlantic Giant pack for under that skips the frills and focuses on size.
Survival Garden Seeds sells this as a no-nonsense entry to growing massive fruit for state fairs. The key feature is the genetics: “Atlantic Giant” is the same lineage that holds world records, and these seeds are described as disease resistant and pest resistant. The expected plant height of 30 feet is a serious warning — this vine needs a lot of space. Buyers report strong early growth, with one mentioning “all of the ones I planted sprouted” and noting these looked better than a competing brand.
The honest trade-off is the variable germination. While some buyers got 100% sprout success, one experienced gardener with decades of experience reported “more like 70% germination and yes i did it right.” Another reviewer felt the seeds were small and produced small vines. This product contains 5 packs of seeds, so the total number of seeds is uncertain. If you lose one or two, you are down to three plants.
The brand is a family-owned US small business, and the seeds are open-pollinated (meaning you can save seeds from your harvest for next year). This is the cheapest true Atlantic Giant pack on this list, but the low seed count makes it a gamble for anyone without a backup plan.
Low-Cost Entry
- True Atlantic Giant genetics for
- Disease and pest resistant traits advertised
- Open-pollinated for seed saving
The Risk
- Mixed germination reports from buyers
- Some buyers question seed authenticity
Perfect for: the budget-conscious grower who already has experience and wants a cheap shot at a giant without spending +.
Think twice if: you are a beginner — 5 seeds with variable germination leaves little room for mistakes.
3. Park Seed Dill’s Atlantic Giant Pumpkin Seeds
The same genetics that broke the world record at 1,810 pounds, sold in a 10-seed pack from a trusted seed house.
Park Seed is a well-known name in the gardening world, and their Dill’s Atlantic Giant is the variety that serious competitors reach for. The claim is bold — “developed from the same genetics as the pumpkin that broke the world record at 1,810 pounds” — and it means this is not a generic “giant” seed. You could theoretically produce a pumpkin in the 400 to 500 pound range. The pack of 10 seeds gives you enough to hedge against poor soil or weather conditions. One buyer in the desert southwest planted 9 out of 10 seeds and watched them survive 30 days of 100°F-plus temperatures.
The major caveat is the germination rate. This is the most-reported subject across the reviews, and it is a mixed bag at best. Some customers got fast, vigorous growth, while others had zero germination. The consensus among owners is that the seeds can be small, and the germination depends heavily on soil temperature and moisture. The product requires spacing of 3 to 5 feet between plants and full sun — it is not a casual weekend project.
What wins people over is the seed quality. Despite the germination gamble, the plants that do survive are described as “fast growing and extremely hearty,” with one vine growing 15 by 15 feet and adding roughly a foot per day. The recommended soil is peat-based, so buying a bag of peat moss alongside the seeds is a smart move.
Competition-Grade
- World-record genetics (1,810 lb lineage)
- 10 seeds per pack — better odds than the 5-packs
- Fast, vigorous vine growth once established
The Gamble
- Germination is the most-discussed pain point — very mixed results
- Seeds are noted as small by several buyers
- Needs 20+ feet of space per plant
Go for it if: you are serious about competing and want the most proven giant-pumpkin genetics from a reputable seed company.
skip it if: you have a short growing season or cannot guarantee consistently warm soil for germination.
4. Big Max Pumpkin Seeds (Marde Ross & Company)
Twenty seeds of the Big Max variety, promising 100-pound-plus fruit for about per seed.
Big Max is a classic heavyweight pumpkin variety, and this pack from Marde Ross & Company doubles the seed count of most competitors at 20 seeds. That is a huge advantage for the price. If you plant half directly in the ground and start the rest indoors, you have a serious buffer against failure. Buyers confirm the seeds germinate quickly and produce healthy vines. One late-season planter started seeds on September 1st and harvested basketball-sized pumpkins by Halloween, which suggests the genetics are solid even with a shortened window.
The complaints are sparse but real. One reviewer noted zero germination across 8 seeds, which is a tough loss. The brand provides minimal growing instructions — just “plant 1 inch deep” — so beginners will need to do their own homework on spacing and fertilizer. The company has been a licensed California nursery since 1985, which adds some credibility.
The real selling point is the seed count. This pack gives you 20 seeds versus the Survival Garden Seeds Atlantic Giant pack’s 5 packs for only a couple of dollars more. For a project that requires multiple plants to find the strongest candidate, this is the most economical way to get there.
Volume Advantage
- 20 seeds — best seed-to-dollar ratio for a single variety
- Proven to produce 100+ lb fruit in the right conditions
- Quick germination reported by most buyers
Lacks Polish
- Minimal growing instructions included
- Occasional complete germination failure
- Brand is less well-known than Park Seed
Best for: the grower who wants to boost the number of shots at a giant pumpkin without spending premium money.
Not for: someone who needs hand-holding through the growing process — this is a seeds-and-go product.
5. Mix Pumpkin Seeds for Planting 10 Variety (EquSym)
A 100-seed variety pack that includes a “Giant” type alongside 9 other favorites — a one-box pumpkin patch.
EquSym packs 100 total seeds into this bag, with 10 seeds from each of 10 varieties. The lineup includes Jack O’ Lantern, Baby Boo, Blue Jarrahdale, and a Giant variety. This is not a pure giant-pumpkin pack, but it gives you a 10-seed shot at a large pumpkin while also growing sugar pies for baking and fairy tales for decoration. The germination rate is advertised as over 90%, and the seeds are from the 2025 season. The instructions recommend soaking the seeds in warm water for more than 4 hours before planting.
The huge advantage here is the number of seeds. Even if the Giant variety only gives you one or two mature plants, you still get a full crop of pumpkins for carving, pies, and decor. One buyer mentioned the seeds sprouted in just 4 days despite armadillos digging in the bed and heavy rain washing them away — that is resilient growth. The packaging is reusable and labeled, which makes it easy to keep track of varieties if you stagger planting.
The honest downside is that the Giant seeds in this mix are not Dill’s Atlantic Giant genetics. You will not break any records with this pack. The germination rate is also not universally perfect — one classroom reported poor results, and another buyer said only 10% of their seedlings grew past a few inches. This is a beginner-friendly collection, but the “giant” component is more of a bonus than the main event.
The bottom line: A massive number of seeds for the price makes this the best pick for a family or classroom wanting a diverse pumpkin patch with one purchase.
Reach for this if: you want a high-volume, low-cost introduction to growing many pumpkin types with a few giant seeds thrown in.
pass on it if: you are laser-focused on growing a single massive pumpkin for competition — you need the Dill’s Atlantic Giant variety exclusively.
6. 200+ Pumpkin Seeds for Planting 10 Variety (EquSym)
Over 200 seeds in individually labeled packets — the ultimate variety pack for the gardener who wants everything.
This is the highest-volume pack in the comparison, doubling the seed count of the 100-seed Mix. It covers the same 10 varieties (Jack O’ Lantern, Connecticut Field, Casper White, Blue Jarrahdale, Fairy Tale, Baby Boo, Sugar Pie, Jack Be Little, Giant, and Yellow Paris), but each variety gets roughly 20 seeds. The packaging is a clear standout — each seed type comes in its own labeled packet inside the reusable bag. Buyers call out that organization as a major plus, making it easy to know exactly what you are planting.
The germination feedback is mixed. While one owner reported “almost every seed grew,” another noted that over half did not germinate and suspected that only 2 to 3 of the labeled varieties were actually represented based on seed appearance. This is a risk with any multi-variety pack at this price point. The company recommends soaking seeds in warm water for over 4 hours before planting, which may improve results.
For the price, the sheer number of seeds means you can afford to lose some to poor germination and still have plenty left. The “Giant” variety in this mix is not a named strain like Dill’s Atlantic Giant, so size expectations should be realistic. This is a quantity-over-specific-genetics play, and it works well for that purpose.
What owners agree on: The organizational packaging is excellent. What they disagree on is whether all 10 varieties are actually in the bag — some buyers suspect variety overlap.
Ideal for: the community garden or school project that needs a high volume of seeds across multiple varieties at a low per-seed cost.
Not the right call for: the grower who needs guaranteed genetics for a competition giant pumpkin.
7. 100 x Dill’s Atlantic Giant Pumpkin Seeds (MySeeds.Co)
A full 100 seeds of record-breaking Dill’s Atlantic Giant genetics — the serious grower’s bulk option.
MySeeds.Co delivers a pure Dill’s Atlantic Giant pack with 100 seeds. This is the only product on the list that gives you a triple-digit count of a single, proven giant variety. The referenced world record of 1,689 pounds gives you an idea of the genetic ceiling. The expected growing period is 120 days, and the seeds are GMO-free for outdoor planting in full sun. Buyers confirm the seeds arrive quickly and begin sprouting within a week of planting.
The biggest weakness is the germination variability at scale. A single review stands out in the data: “4 seeds was good out of 100.” That is a severe blow if true. Other owners mention high germination rates and fast growth, so the experience appears inconsistent. At a per-seed cost of roughly, this is the most affordable option for bulk giant-pumpkin seeds — but only if the germination rate is decent in your conditions.
One other consideration: the USDA hardiness zone is listed as zone 6, which is a narrower range than the CZ Grain mix (zones 3-10). Growers outside that zone may see lower success. The moderate watering needs and 120-day growth cycle mean you need a long, warm season to reach full size.
Bulk Power
- 100 seeds of true Dill’s Atlantic Giant genetics
- Lowest per-seed cost in the comparison
- Proven record-breaking lineage (1,689 lb)
Volume Risk
- Germination rate varies dramatically — 4% in one case
- Narrow hardiness zone (6) may limit growing regions
- 120-day growth cycle requires a long season
Get this if: you have the space and the season to plant 100 seeds and select the strongest 5-10 vines for competition.
Pass if: your growing window is short or your zone is outside 6 — the 120-day requirement is a hard constraint.
Understanding the Specs
Seed Count vs. Germination Rate
More seeds give you a bigger safety net. A pack of 5 seeds where only 3 sprout leaves you with very little room for mistakes in watering or pest control. A pack of 100 seeds lets you cull weak seedlings and focus on the strongest plants. The advertised germination rate is a best-case number — real-world conditions (soil temperature, moisture, pests) always lower it.
Dill’s Atlantic Giant Genetics
This is the only variety that has produced world-record pumpkins. If you see “Big Max” or “Giant” without “Dill’s Atlantic Giant” or “Atlantic Giant,” the maximum potential size is significantly lower. These seeds grow vines that can spread 15 to 20 feet, so plan your garden layout accordingly.
