Hostas are herbaceous perennial plants, growing from corms or rhizomes, with broad lanceolate or ovate leaves varying widely in size by species from 3–40 cm long and 2–30 cm broad. Variation among the numerous cultivars is even greater, with clumps ranging from less than 10 cm across to more than 2 m across. The lily like flowers are produced on an erect panicle up to 80 cm tall; the individual flowers are usually pendulous, 2–5 cm long, with six tepals, white, lavender, or violet in colour and usually scentless. Hostas are native to China. Flowering: August-September.
