Perennial & Biennial Plants


In this range you'll find an impressive selection of perennial plants and biennial plants, which are perfect for beginners and experienced gardeners alike. Also known as herbaceous plants, perennial plants live for 2 or more years and flower every year. Biennial plants live for up to 2 years, flowering profusely in their second year before setting seed and dying. Both are great for beds and spring displays and there are many delightful plants to choose from. Use the selections in the left menu to select the right plants for your garden.

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").
