What is a perennial plant?

Perennial plants live for several years and flower every year. Choose from a wide range of perennials including half-hardy, climbing, and evergreen perennials for spectacular garden displays.

What is a biennial plant?

Biennial plants live for up to 2 years, flowering profusely in the 2nd year before setting seed. Browse our biennial plants collection including a fabulous assortment of foxgloves.

When to plant perennials

Perennial plants are best planted in spring or autumn. Perennial seeds will need sowing a little earlier and under cover before planting out. Be sure to check the specific growing and sowing instructions provided for each plant. Visit our perennial plant care and advice pages for more guidance.
