'Delfino' Cilantro ( Coriandrum sativum) is an aromatic, edible herb, and unlike other Corianders has unique, fine fern-like foliage. The flavor resembles a strong parsley taste with citrus and is perfect for any recipe requiring finely chopped leaves. Foliage can be kept fresh in a glass of water for as long as a week, if the water is changed often. The small white blooms of the plant have the same taste and are a good addition to salads. The seed, of course, is the spice coriander. PIcturesque in the garden, the plant grows to about 20 inches high.
