A large shrub-like perennial, generally grown as the cultivar L. olbia "Rosea'.
Several plants are grown as perennials and their identification may be difficult especially as hybridisation may have occurred:
L. cachemiriana Cambess. from Kashmir may be grown as an annual to 2 m or so tall with deeply cleft petals to 4 cm long;
L. thuringiaca L. from Europe, which grows to about 1.5 m tall, is grey-hairy with purplish pink petals and may be supplied as cultivars of varying habit and flower tonings.

Flowers solitary or in pairs, large, prolific on stalks generally more than 1 cm long. Petals more than 4 cm long.
Possibly of pre-1920s hybrid origin in the UK (L cachemiriana × L. thuringiaca).
