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.
