FRITILLARIA, FRITILLARY: A genus of the monogynia order, belonging to the hexandria class of plants; and in the natural method ranking under the 10th order, Coronaria. The corolla is hexapetalous and campanulated, with a nectariferous cavity above the heel in each petal; the stamens are as long as the corolla. There are five species, all of them bulbous-rooted flowery perennials, producing annual stalks from about one foot to a yard or more high, terminated by large, bell-shaped, liliaceous flowers, of a great variety of colours. They are all propagated by offsets, which they furnish abundantly from the sides of their roots, and which may be separated every second or third year; they are hardy plants, and will thrive in any of the common borders.
