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.

Foxglove 'Illumination Chelsea Gold'

Digitalis

To celebrate our Best New Plant success at the RHS show, we have named our new Foxglove 'Illumination' variety 'Chelsea Gold'. Just like its pink cousin, this spectacular foxglove is completely sterile, giving it an incredibly long flowering period as it won't set seed. Unlike most foxgloves which are generally biennial, this half-hardy semi-evergreen is a true perennial so you will be able to enjoy its flowers for years to come. The exotic looking blooms are densely packed on sturdy stems, with many side branches, making a striking addition to summer borders. Height: 90cm (36"). Spread: 45cm (18").
