Phaseolus vulgaris Item #0228 58 days. These delicate French filet beans are no longer a luxury item found only in gourmet restaurants. You can enjoy their superb, tender flavor fresh from your garden all summer long. Filet (or as the French say, “haricot verts”) are slender beans. They are juicy and delicious when picked pencil-thin at only 1/4″ in diameter and 4.5″ long. Steam or saute for just a minute and enjoy. Easy and delicious. This packet sows three 9-foot rows.
