If you are looking for a bush bean that produces heavy yields of tender, flat, stringless pods rather than the standard round green beans, the Roma II is a proven Italian heirloom cultivar that delivers exactly that. This is the bean for gardeners who want a reliable, high-volume crop that cans beautifully, freezes without turning mushy, and offers a rich, earthy flavor that holds up in soups and stews.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. For this guide, I dug into technical growing specs, seed counts per pound, germination rates reported by real buyers, and side-by-side comparisons of days to maturity and pod dimensions to rank the best options for home gardeners.
After sorting through dozens of seed lots and analyzing hundreds of verified owner reports, I found the five top performers that earn a spot on this list of the best roma ii bush beans for reliable, high-yielding harvests.
How To Choose The Best Roma II Bush Beans
Roma II bush beans are a specific cultivar of Phaseolus vulgaris known for their flat, 4-to-5-inch stringless pods and compact 16-to-20-inch growth habit. Unlike vining pole beans, they require no trellis and mature as a single flush, making them ideal for raised beds and succession planting. When selecting seed, focus on four factors that directly determine your harvest weight and quality.
Days to Maturity and Your Growing Window
Roma II typically reaches full harvest in 55–65 days from direct sowing. If your growing season is short, a cultivar that matures on the faster side of that range (near 55 days) reduces the risk of frost cutting production short. In hotter climates, slower-maturing beans (toward 65 days) may produce a heavier second flush if temperatures stay below 90°F.
Seed Count per Pound and Sowing Density
A standard pound of bush bean seeds contains roughly 1,400 to 1,600 seeds. For a continuous harvest, plan on 8 to 10 seeds per foot of row. Cheaper packets with extremely low seed counts (under 300 seeds per pound-equivalent) often perform poorly when scaled up for full-season canning or freezing. Always check the listed weight and estimated seed count before buying.
Germination Rate, Not Just Brand Reputation
Bush bean seeds lose viability quickly if stored in hot or humid conditions. An heirloom or non-GMO label alone does not guarantee a high germination percentage. Look for seed lots with recent harvest dates and verified buyer photos showing uniform sprouting within 7–10 days. A single negative review citing 1% germination is a stronger signal than twenty positive reviews for a different batch.
Pod Quality for Your Intended Use
Roma II’s defining trait is its wide, flat, stringless pod. If you plan to can or freeze the harvest, choose a lot verified to produce pods that stay tender and do not develop tough strings as they reach full length. Some seed sources sell cross-pollinated or mislabeled seed that yields round pods with strings. Look for reviews that specifically mention “flat,” “stringless,” and “cans well” to confirm pod type.

In‑Depth Reviews
1. Roma II Bush Bean Seed (5 Lb)
This 5-pound bulk bag from Mountain Valley Seed Company is the most cost-efficient way to plant a serious Roma II crop. At roughly 1,400 seeds per pound, this single bag gives you enough seed (around 7,000 seeds) to plant a 700-foot row — more than enough for a family’s entire canning and freezing season. Verified buyers in zone 6b reported harvesting 6-plus gallons of flat, stringless pods from just 8 ounces of these seeds, with heavy flushes continuing as long as pods were picked regularly.
The Roma II cultivar matures in about 60 days from direct sow and produces 4-to-5-inch wide, flat pods that stay tender and stringless even at full size. Multiple buyers confirmed the beans cans well, freezing without turning tough. The seeds are non-GMO, heirloom, and open-pollinated, which means you can save seed from your best plants for next year. The 5-pound weight also makes this the best value per seed on this list.
Seasoned gardeners will appreciate that the Mountain Valley brand seeds arrived safely packaged with detailed growing information. One buyer noted the beans are “easy to can and easy to stick with a fork,” which speaks to the firm texture that holds up during processing. If you have the garden space, this bulk purchase pays for itself in a single season.
What works
- Exceptional value per seed at 5 lbs total weight
- Verified heavy yields — 6+ gallons from only 8 oz
- True flat, stringless pods confirmed by multiple growers
What doesn’t
- Large bag requires proper cool, dry storage to maintain viability
- Some buyers may prefer smaller trial-size packets first
2. Blue Lake Bush Bean 274 Seeds (1 Lb)
Although not a Roma II, the Blue Lake 274 is the most consistently praised bush bean in this comparison, with nearly all 5-star reviews citing nearly 100% germination within a week. The seeds are heirloom, non-GMO, and open-pollinated, producing dark green, round pods about 5.5 inches long on compact 16-inch plants. Buyers in USDA zone 9 reported excellent germination and a heavy yield of crisp, sweet beans with zero pest or disease issues.
The 1-pound bag contains 274 seeds, which is a lower seed count than the volume-focused options, but the approximately 87 seeds per ounce means a high percentage germinated under standard soil conditions. One grower planted only 35 seeds and still had plenty left to share. The variety is naturally resistant to Bean Common Mosaic Virus and tolerates NY15, giving it an edge in disease-prone regions.
This is an ideal choice for gardeners who prioritize reliability and flavor over raw seed quantity. The Blue Lake brand has decades of proven performance in home gardens, and these seeds are from Mountain Valley Seed Company, the same supplier as the top pick. However, the round pod shape means it is not a flat Italian bean, so adjust expectations if your goal is strictly Roma II pod type.
What works
- Exceptional germination rates — near 100% in buyer reports
- Disease resistant to common bean mosaic virus
- Crisp, sweet flavor ideal for fresh eating
What doesn’t
- Round pods, not flat Italian Roma type
- Only 274 seeds per pound — less volume than other options
3. Contender Bush Bean Seeds (1 Lb)
The Contender bush bean, sometimes called Buff Valentine, is the fastest-maturing option in this lineup at just 49 days to full harvest. For northern gardeners with short summers or anyone wanting an early bean before the main Roma II crop comes in, this is a strong pick. The 1-pound bag contains roughly 1,400 seeds, giving you enough to plant a 150-foot row with room for succession sowing.
Buyer feedback is overwhelmingly positive, with multiple reports of every seed germinating and producing 40 pounds of beans from just 3/4 pound of seed over eight weeks in southwest Florida. The beans were described as stringless and great-tasting, with no tough fibers even when left on the plant a bit longer. The seeds are non-GMO, heirloom, and open-pollinated from Mountain Valley Seed Company.
The Contender is a round-podded bean, so it will not give you the flat Italian shape that Roma II fans prefer. However, its extremely short maturity window and high germination rate make it a reliable workhorse for beginning gardeners or anyone who worries about late frosts. It also runs slightly more vine-like than compact bush beans, so expect some spreading growth.
What works
- Fastest maturity at 49 days — ideal for short seasons
- Incredible germination rate with nearly 100% reported
- High yield per seed — 40 lbs from 0.75 lb of seed
What doesn’t
- Round pods, not flat Italian bean type
- Plants may run slightly, requiring more ground space
4. Roma II Bush Beans (500 Count)
This 500-count packet from Country Creek Acres is marketed specifically as Roma II, with flat green pods described as ideal for canning, freezing, or eating fresh. The price per seed is higher than the bulk options, making this a trial-sized purchase for gardeners who want to test the Roma II cultivar before committing to a larger bag. The seeds are non-GMO.
Buyer experiences are sharply divided. Several reviews confirm that the beans do produce flat, stringless pods that can well, with one repeat buyer saying they “love Italian Romas” and find them easy to can and eat with a fork. However, a significant number of negative reviews report alarming germination failures. One buyer with two college degrees in production agriculture reported only 1% germination, and another saw just 3 sprouts from the entire 500-seed packet in their fall garden while everything else around them grew fine.
This variability suggests the seed lot may have been stored improperly or was from an older harvest. If you buy this packet, do a quick test germination on a damp paper towel before committing soil space. The positive reviews about pod quality are genuine, but the germination risk is higher than the Mountain Valley bulk options. This is an entry-level pick best suited to gardeners willing to accept that risk for the chance of flat Roma pods.
What works
- True flat Roma II pod shape when seeds do germinate
- Pods can well without turning mushy
- 500 seeds is a manageable trial size
What doesn’t
- Multiple reports of extremely low germination rates
- Higher cost per seed compared to bulk options
5. Romano Qing Bian Pole Bean Seeds (4 Oz)
This is not a bush bean — it is a pole bean variety of the Romano type, meaning it requires a trellis, fence, or pole support to grow vertically. The Kitazawa Seed Company pack contains about 236 seeds (4 oz) and produces long, flat green beans that are popular in Asian and Mediterranean cooking. Buyers who grew these for a fall crop reported loving the flat bean texture, noting they “missed the flat green beans that were everywhere in Europe.”
The seeds are heirloom, non-GMO, and open-pollinated. The germination window is 7–10 days, and plants reach full maturity in 60–70 days. One buyer found the seeds arrived in good quantity and all germinated, while another reported zero germination from the entire pack. This split mirrors the Country Creek Acres experience and points to the difficulty of verifying seed storage conditions for smaller brands.
If you have vertical garden space and prefer a climbing flat bean over bush-type growth, this is the only pole bean option on the list. The flat pods are ideal for stir-fries and fresh use, and the climbing habit allows you to grow more food in a small footprint. However, the mixed germination reviews make it a gamble unless you are prepared to do a pre-germination test.
What works
- Authentic flat Romano bean shape for European-style cooking
- Climbing habit saves ground space with vertical support
- Good for fall succession planting in warm climates
What doesn’t
- Mixed germination reports — some packs had zero sprout
- Requires trellis or pole support, not a bush bean
Hardware & Specs Guide
Days to Maturity
Bush bean cultivars vary from 49 days (Contender) to 65 days (Blue Lake 274). Roma II sits near the middle at approximately 60 days. This window matters because, unlike indeterminate pole beans, bush beans produce their entire crop in a single flush over about two weeks. Choosing a maturity window that fits your growing season ensures you do not lose your entire harvest to an early fall frost.
Seed Count Per Pound vs Pod Shape
A standard pound of small round-podded beans (Blue Lake, Contender) contains roughly 1,400–1,600 seeds. Roma II’s larger flat seeds are heavier per seed, so a pound may yield fewer individual seeds — typically in the 1,200–1,400 range. Buyers who prioritize pod shape should look for “flat” and “stringless” descriptors in reviews, not just the cultivar name, because mislabeling does happen.
