They are grown for their foliage and flowers, they have usually arching stems and alternate, opposite, or whorled, linear to broadly elliptic or ovate, parallel-veined leaves that turn yellow in autumn. Mostly pendent, sometimes erect, tubular to bell shaped, mainly white or cream, occasionally purple-pink flowers, with green markings, are either solitary or borne in small cluster, often along the lower sides of the stems. Flowers are usually followed by berry like, spherical, red or black fruits. Solomon’s Seals are suitable for a shady mixed or herbaceous border, or for a woodland or rock garden.
