Foxglove 'Illumination Collection'

Digitalis

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 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.
