Paeonia mascula subsp. russoi has lovely large, violet-pink flowers over greyish green biternate leaves. It comes mainly from Mediterranean islands, from Spain to western Greece. It is sometimes labelled P. russii, but the name russoi is correct, and refers to a Sicilian botanist, Father Joachim Russo. It has also been called P. corallina var. pubescens, which tells us that the leaves are somewhat hairy on the under side.
Pictured here at RHS Wisley last April. A while yet before it flowers this year I should think.
