Phaseolus vulgaris 'Romano'
vegetableWide flat Italian green beans with meaty, tender pods and a richer, more complex flavor than round snap beans. A staple of Italian cooking — excellent sauteed with garlic and olive oil, braised slowly, or added to minestrone. More forgiving of harvest timing than standard snap beans — pods stay tender longer. Both bush and pole varieties exist.

When to Fertilize
Inoculate seeds; no additional nitrogen needed
Fertilizer
Low-nitrogen compost worked in before planting; no additional nitrogen
Direct sow after last frost when soil is above 60 F. Romano beans need consistent warm temperatures to produce well. Bush types need no support; pole types need a trellis. Unlike snap beans, Romano pods can be left on the plant a few extra days without becoming tough — the wide flat shape stays tender longer. Pick when pods are 5 to 6 inches and still bright green.

Row cover early season; handpick adults and larvae; neem oil spray
Water blast; insecticidal soap; parasitic wasp habitat nearby
Avoid overhead watering; ensure airflow; remove infected leaves; copper spray
Pyrethrin spray if severe; row cover early
Pick pods when flat and 5 to 6 inches long before seeds start bulging noticeably. Romano beans are forgiving — pods that would be over-mature on a standard snap bean are still pleasant on Romano types. Blanch and freeze excess production. Excellent eaten young whole or broken into pieces in pasta dishes and soups.
Good source of fiber, folate, potassium, iron, and vitamins A, C, and K when eaten as a fresh snap bean. Higher in phytonutrients when the pods are young and bright green. Provides plant protein and complex carbohydrates when eaten as a dry bean.
