A perennial herb which is naturalised on rocky limestone slopes. On Steep Holm (N. Somerset) it grows on the steep eastern slopes of the island, where there is some protection from westerly gales. Lowland.
This species was discovered on Steep Holm (N. Somerset) in 1803, where it was once considered to be native. One plant was found on Flat Holm (Glamorgan) in 1982. There is a 19th-century record from the mainland, near Bath (W. Gloucs.). Although formerly quite plentiful on Steep Holm, plants were collected by gardeners in the 19th century and their numbers have been further reduced more recently by the spread of Acer pseudoplatanus. The population is now dependant on conservation management for its survival. Many other Paeonia populations are recorded as this species, but all are referable to P. officinalis or P. lactiflora.
Native of S. Europe and S.W. Asia.
