Symphytum (Greek, to grow together, in reference to the supposed healing virtues), Boraginaceae. Comfrey. Erect often hispid herbs, usually hardy in all but the far North, sometimes grown for the variegated foliage of some species. Roots sometimes tuberous: lvs. alternate or several radical ones; the cauline sometimes decurrent; the upper sometimes strongly approximate, almost opposite: cymes terminal, usually single or twice bifid or simple unilateral racemes: fls. yellowish, blue, or purplish, pedicelled; calyx 5-cleft or -parted, lobes or segms. linear; corolla broadly tubular, lobes 5, very short; stamens 5; ovary distinctly 4-lobed: nutlets 4, obliquely ovoid, erect, rugose.—About 25 species, Eu., N. Afr., and W. Asia. Monographed by C. Bucknall in Journal of the Linnean Society, vol. 41 (1913). Of easy cult. in any good soil. The shade of overhanging trees is not objectionable. When grown for the beauty of the variegated foliage, the flowering sts. may be removed with advantage. Useful in borders. CH The above text is from the Standard Cyclopedia of Horticulture.
