Geranium maderense, known as giant herb-Robert ^[2] 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 . ^[3]

Growing to 120–150 cm (47–59 in) tall and wide, it is a mound-forming evergreen biennial or triennial with deeply divided ferny leaves. Spectacular pink flowers on hairy red stems are produced in large panicles in summer. ^[4] It is grown as an ornamental plant in temperate regions, where it is hardy in mild or coastal areas down to −5 °C (23 °F). It has gained the Royal Horticultural Society's Award of Garden Merit. ^{[5] [6]}
