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.
