Rhizomatous perennials grown for their foliage and flowers. Usually, they have arching stems, and linear to ovate, parallel-veined leaves that turn yellow in autumn. Flowers are mostly pendent, tubular to bell-shaped, mostly white or cream, sometimes purple-pink, with green markings, being solitary or in small clusters. Flowers usually followed by berry-like, spherical, red or black fruits. Good for borders, woodland or rock gardens. Best in full or partial shade and fertile, moist, well-drained soil.
