From a short, stout trunk it builds a spectacular architectural rosette of huge, finely cut palmate leaves, then erupts into a vast dome of magenta-pink flowers that can smother the whole plant. Native to the island of Madeira, it is the giant of the geranium world and a true focal point for a warm, sheltered corner.\u003c\/p\u003e\u003cp\u003eThis is a statuesque, short-lived exotic best understood as a biennial or monocarpic perennial. It spends its first year or two building that bold evergreen rosette, flowers gloriously in late spring and early summer, then sets seed and fades, leaving a scatter of self-sown seedlings to carry on. Rated RHS H3, it is happiest in the mildest, most sheltered gardens and coastal spots, where it can be grown outdoors year round with winter protection in colder areas.
