Cichorium intybus 81 days. Add a dazzling color combination, crisp texture, and a sweet-bitter flavor to enhance your cool-weather salads. Dense, round, 4-5 inch heads have brilliant red leaves with pearly white midribs. Leonardo is very quick to size up and is a great choice for late summer and fall plantings, as the best tasting and most colorful crops mature in cooler temperatures. Approximately 80 seeds per ⅛ gram.
