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.

Rose Lily Grass

Rhodohypoxis

Dainty, jasmine-like flowers in two shades of pink erupt in profusion above short clumps of lance-shaped foliage in late spring, followed by flushes of flowers throughout the summer.

Each Rose Lily Grass plug plant contains more than one bulblet for prolific flowering in borders, rock gardens and containers. Although fully hardy, Rhodohypoxis will need protection from winter wet.
