Wahlenbergia (named after Georg Wahlenberg, 1780-1851, Swedish botanist). Including Edraianthus (Hedraeanthus). Campanulaceae. Annual or perennial herbs, base of the stems sometimes woody, used as greenhouse and border plants, mostly the latter. Leaves alternate, rarely opposite: infl. usually irregularly centrifugal; peduncles terminal, lateral or axillary, solitary or rarely paniculate: fls. usually blue and nodding; calyx-tube adnate, hemispherical, turbinate or obconical-oblong, limb 5-parted, very rarely 3-4- merous; corolla campanulate, funnel-shaped, tubular or rather rotate, 5-cleft, very rarely 3-4-cleft; ovary inferior or semi-superior, 2-5-celled: caps. erect, loculicidally 5-valved.—About 110 species, Eu., Medit. region, S. Afr., and Trop. Amer. This treatment includes Edraianthus, which is often kept as a distinct genus. The species are used mostly as rock-garden plants, and receive the treatment given campanulas. W. gentianoides, Hort., is offered in the trade as a rock-plant growing a foot high, with erect wiry sts. and bright blue fls.—W. grandiflora, Schrad., is Platycodon grandiflorum.
