Geranium maderense, known as giant herb-Robert or the Madeira cranesbill, is a species of flowering plant in the family Geraniaceae, native to the island of Madeira. It is sometimes confused with another Madeira endemic, Geranium palmatum.[1]
Growing to 120- tall and wide, it is a mound-forming evergreen perennial with deeply divided ferny leaves. Spectacular pink flowers on hairy red stems are produced in large panicles in summer.[2] It is grown as an ornamental plant in temperate regions, where it is hardy in mild or coastal areas down to -5C. It has gained the Royal Horticultural Society's Award of Garden Merit.[3] [4]
