Digitalis x valinii

  • New colour break
  • Multi-flowering Foxgloves
  • Prennial habit

The Digitalis Illumination Series, from our very own breeding programme, has changed the world of Foxgloves; taking them from a wiry, brief-blooming biennial wildflower to a handsome, tidy yet shrubby perennial with true garden performance.

Following several outstanding colour developments, our breeding team has done it again with the creation of a brand new colour break. Digitalis 'Illumination Ruby Slippers' is the latest addition to our award winning series. This beautiful foxglove produces multiple spires of open-mouthed blooms on short stocky plants that are just as at home in a patio pot as a cottage garden border scheme. Being completely sterile, this stunning Foxglove won't set seed, making it incredibly long flowering. As the main flower spike fades, multiple sideshoots spring up to offer five months of vivid floral colour. Parentage from the little-known Isoplexis (Canary Island Foxglove) gives this exciting new Digitalis its fabulous colouring and perennial habit. Height: 90cm (36"). Spread: 45cm (18")
