This is one of the most sought after hardy geraniums. Very large, deeply toothed foliage forms a magnificent clump up to 1.2m in ideal conditions. 4cm bowl-shaped sizzling magenta flowers with black veins and a black eye put on a show right through from late spring to Autumn Gorgeous when planted with silver foliage, lemon flowers or the cool blue of G. pratense. Very hard to find. Sun to semi-shade and fertile soil. Winter dormant.
