Foxglove 'Illumination Chelsea Gold'

Foxglove 'Illumination Chelsea Gold'

  • NEW in 2013
To celebrate our Best New Plant success at the RHS show, we have named our new Foxglove ‘Illumination’ variety 'Chelsea Gold'. Just like its pink cousin, this spectacular foxglove is completely sterile, giving it an incredibly long flowering period as it won’t set seed. Unlike most foxgloves which are generally biennial, this 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").
