Any of about 40 species of hardy herbaceous perennials, also called plantain lily, of the genus Hosta, in the agave family (Agavaceae), native to eastern Asia. They prefer light shade but will grow under a variety of conditions. They are frequently grown for their conspicuous foliage, which may be light to dark green, yellow, blue, or variegated. The ribbed leaves grow in a cluster at the base, and stalks bearing clusters of tubular white or bluish-purple flowers emerge from the leaves.
