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.

Daylily 'Super Summer Mixed'


  • New in 2014
  • The spectacular Day Lily

The magnificent, showy trumpets of Daylily 'Super Summer Mixed' are carried on stiff stems above clumps of decorative, strappy foliage. The colourful lily-like blooms, each lasting only a day, are produced so freely that you will be able to spare a few stems for a short-lived arrangement of daylily flowers indoors. Daylilies are reliable hardy perennials, equally at home in cottage gardens or exotic borders where they are quick to establish and easy to maintain. Height and spread: 45cm (18").

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
