Foxglove 'Illumination Pink'

Digitalis

 Customer Rating
  • Winner of Plant of the Year 2012 - RHS Chelsea Flower Show, Best new product at the Anglian Business Awards, Best new product at the Garden Retail awards
  • T&M's own breeding

Thought to be an impossible hybridisation, this is the most spectacular foxglove you will have ever seen! Parentage from the little-known Isoplexis (Canary Island Foxglove) gives this exciting new Digitalis its fabulous tropical colouring. Being completely sterile Foxglove ‘Illumination’ won’t set seed, giving it an incredibly long flowering period. 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").
