Perovskia (after B. A. Perovski, about 1840, governor of the Russian province Orenburg). Also spelled Perowskia. Labiatae. About 4 herbaceous or shrubby plants from Cent. Asia, allied to Salvia, with opposite serrate or pinnatifid lvs. and rather small heterostylous fls. in whorls usually arranged in terminal spikes: calyx tubular-campanulate, 2-lipped; corolla 2-lipped, the upper lip unequally 4-lobed, the lower undivided; 2 sterile and 2 fertile stamens, the latter with 2 distinct contiguous anther-cells: fr. consisting of 4 ovoid- oblong nutlets inclosed by the calyx. The only species in cult, is P. atriplicifolia, Benth. Shrub, to 5 ft., erect, of aromatic sage-like odor when bruised: sts. hoary- tomentose: lvs. ovate-lanceolate to lanceolate, acutish, unequally and coarsely serrate, at first pubescent, finally nearly glabrous, glandular, 1 1/2-2 1/4 in. long: fls. blue, about 1/3in. long, in 2-6-fld. remote whorls arranged in slender spikes forming terminal panicles 1-1 1/2 ft. long; calyx densely villous. Aug., Sept. Afghanistan to W. Himalayas and W. Thibet. B.M. 8441. R.H. 1905:344. G. 33:511; 36:539—Handsome shrub, valuable for its late blue fls. forming a pleasing contrast with the silvery gray sts. Not quite hardy N., but if killed partly back, it sends forth young shoots which will flower the same year. It prefers sunny positions and well-drained loamy soil. Prop, is usually by greenwood cuttings, which grow readily in summer under glass. Alfred Rehder. CH
