Roma II Bush Bean is an easy to grow open-pollinated descendant of the classic heirloom Romano variety. Developed in 1978 to preserve the traditional Roma’s rich, full flavor and flat Italian-style pods, Roma II also offers improved resistance to common bean diseases and excellent yield potential. This compact bush type produces tender, meaty, stringless pods about 5–6 inches long that hold up beautifully when cooked or canned. A favorite for both fresh eating and preserving, Roma II delivers classic Italian garden flavor in a hardy, dependable form that thrives in a wide range of climates.

~ Sowing ~
When to Sow Outside:
Sow directly outdoors after all danger of frost has passed and soil has warmed to at least 60°F. Beans are frost-sensitive and should not be planted too early in cool or wet soil.
When to Start Inside:
Not recommended; beans transplant poorly and are best direct-sown.
Days to Emerge:
7 - 10 days
Seed Depth:
1 inch deep
Seed Spacing:
Plant seeds 2 - 4 inches apart in rows or blocks.
Row Spacing:
18 - 24 inches apart
Hardiness:
Frost-sensitive annual.
~ Growing ~
Soil:
Prefers loose, well-draining, fertile soil with good organic content. Avoid nitrogen-heavy fertilizers, which can encourage leafy growth over pod production.
Watering:
Keep soil consistently moist but never waterlogged, especially during flowering and pod development. Water at the base to avoid wetting leaves.
Light and Temperature:
Thrives in full sun and warm temperatures between 70°F and 85°F. Protect young seedlings from unexpected cold snaps.
Maintenance:
Low-maintenance plant. Mulch around the base to retain moisture and suppress weeds. Pick pods frequently to encourage continued production.
Container Friendly:
Yes, suitable for large containers or raised beds. Use a container at least 12 inches deep with good drainage.
~ Harvesting ~
When to Harvest:
Harvest pods when they are 5–6 inches long, bright green, and still tender. Avoid waiting too long, as older pods may become fibrous.
How to Harvest:
Gently snap or cut pods from the plant to avoid damaging stems. Check plants every few days for new pods during peak production.
Drying and Storing:
Use fresh for best flavor, or blanch and freeze for long-term storage. Roma II beans also hold up well to canning.
Edible Use:
Delicious steamed, sautéed, or simmered in soups and stews. Their flat pods absorb sauces beautifully and maintain texture when cooked. Excellent for Italian-inspired dishes.
~ Seed Saving ~
Seed Collection:
Allow a few pods to mature fully and dry on the plant before harvesting for seed.
Seed Cleaning:
Remove beans from pods once completely dry and store in a breathable container until fully cured.
Seed Storage:
Store in a cool, dry, dark place. Seeds remain viable for up to 3 years under proper storage conditions.
~ Additional Information ~
Forage for Pollinators:
While beans are largely self-pollinating, their blooms can attract small bees and beneficial insects.
Origin:
Roma II was released in 1978 by the USDA Agricultural Research Station in Idaho as an improved strain of the heirloom Italian Roma bean.
Nomenclature:
The name “Roma” references its Italian heritage and wide, flat “Romano” style pods favored in Mediterranean cooking.
History:
The original Roma bean was brought to the U.S. by Italian immigrants in the early 20th century and became a staple in home gardens for its robust flavor and reliability. Roma II continues that tradition, combining heirloom flavor with modern disease resistance.
Potential Toxicity:
Non-toxic. Raw beans, like all Phaseolus varieties, should be cooked before consumption.
Climate Adaptability:
Performs well across a range of climates; heat-tolerant but prefers moderate humidity. Avoid overly wet conditions.
