摘要

Eustoma exaltatum ssp. russellianum (Fig. 1), also known as lisianthus, is a perennial herb belonging to the gentian family. It is native to Mexico, the southern United States and the north of South America, but is now particularly popular in the cut-flower market. Lisianthus is characterized by bluish-green leaves and extremely flamboyant flowers that can be purple, blue, white, pink, or yellow. The flowers are bell-shaped and upright, and occur singly at the ends of link stalks from short branches near the top of the plant.
