description

The Perovskia species grow as aromatic, fragrant subshrubs . The branches and buds are bare or thickly covered with gray-white star hairs. Terminal buds are missing. The leaves are arranged opposite each other, with entire margins, sawn or pinnate.

The flowers grow to two to four, rarely up to six, in pseudo whorls . On young twigs these are united in 30 to 45 centimeters long, terminal, panicle-like inflorescences . The flowers are sessile or have a short stalk.

The hermaphrodite flowers are five-fold with a double flower envelope . The calyx is bell-shaped, densely hairy and two-lipped. The upper lip is more or less entire to three-toothed, the lower lip bidentate, very hairy and puffed up at the time of fruiting. The corolla is blue-violet, rose-colored, yellowish or rarely white, twice as long as the calyx, funnel-shaped and two-lipped. The upper lip is unevenly four-lobed with two smaller central lobes, the lower lip is oval-ovate and with entire margins. Four stamens are formed, two of them fertile and splayed, two sterile, small and lying under the upper lip. The ovary is twofold and divided into four chests by additional partitions. Four brown, obovate, blunt and bald nuts are formed as fruits, which are surrounded by the white felt calyx.

Systematics and distribution

The genus Perovskia belongs to the tribe Mentheae in the subfamily Nepetoideae within the family of Labiatae (Lamiaceae). The genus Perovskia was first described by Grigori Silytsch Karelin in 1841 . The generic name chosen by him Perovskia reminds of the Russian general and governor of the Orenburg province Vasily Alexejewitsch Perowski (1794-1857).

According to the WCSP, however, the genus is better integrated into the Salvia genus .

The distribution area of ​​the Perovskia species lies in Asia and extends from the northeast of Iran to Balochistan and the northwest of the Himalayas .
