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.

Penstemon 'Strawberries & Cream'

This popular hardy perennial deserves a prime spot in the garden. White trumpet shaped flowers with delicately speckled throats appear in summer above a flush of glossy, semi-evergreen foliage. The long-lasting blooms of Penstemon 'Strawberries and Cream' continue well into autumn, long after other plants have run out of steam. Undemanding and easy to grow, Penstemons tolerate almost any position in the garden, regardless of rain or drought, and even resist slug damage. What more could you ask of a plant? Height: 80cm (31"). Spread: 45cm (18").
