Geranium maderense

Giant Herb Robert, Madeira Cranesbill

  • RHS Award of Garden Merit
  • The palm tree geranium
Geranium maderense is a magnificent tender perennial. The Madeira Cranesbill is the largest of the Geranium species, and certainly one of the most impressive, reaching a height of 1.5m (4',9"). Although perennial, it often acts as a biennial, producing pretty magenta pink blooms in its second year. But you won't mind the wait - it will give you time to appreciate the exotic-looking, dissected, evergreen foliage that radiates from a stout central trunk. This spectacular RHS AGM species will need some winter protection so it is best grown in the conservatory or a large patio container which can be moved to a frost free position in winter. Height: 150cm (59"). Spread: 100cm (39").
