Phaseolus vulgaris Item #3082 54 days. Succulent and tender, Tavera was developed specifically for restaurants, but will be any chef’s favorite. These “haricot verts” (French for narrow green beans) are superb when harvested frequently at a petite size – about 1/4″ wide. You will easily impress your fellow gourmets!
