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 Duo'

Digitalis

  • T&M's own breeding

Parentage from the little-known Isoplexis (Canary Island Foxglove) gives these exciting new Digitalis their fabulous tropical colouring. Being completely sterile Foxglove 'Illumination Duo' won't set seed, making them incredibly long flowering. Unlike most foxgloves which are generally biennial, these half-hardy semi-evergreen varieties are true perennials so you can enjoy them year after year. 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").

  • Collection comprises:
  • Foxglove 'Illumination Pink' - Awarded 'Best New Plant' at the Chelsea Flower Show 2012.
  • Foxglove 'Illumination Chelsea Gold' - The latest addition to the 'Illumination' range, with exotic looking peachy-orange blooms.
