About

Geranium wlassovianum, Wlassov's cranesbill, is a clump-forming, softly hairy, herbaceous perennial maturing to about 60 cm with loose sprays of long-lasting, purple-pink or pink flowers from midsummer to early autumn. The leaves flush purple-bronze in spring and summer, turning red in autumn, giving three-season ornamental value. An excellent border cranesbill.
