Hosta Canadian Blue

Plantain Lily

Lush blue foliage

A bold and beautiful hosta with strong, heart-shaped, veined leaves of striking colour. The foliage becomes more intensely frost-blue as the season progresses forming a medium-sized mound. In summer strong stems carry fragrant lavender-grey, bell-shaped flowers. A striking architectural foliage plant with sleek, elegant lines; perfect for simple, contemporary planting schemes as well as traditional settings.


Best in semi-shade; avoid sunny situations as the colour changes to yellow-green. Good in beds and borders and ideal under the light shade of deciduous trees. Good in a pot or container.


Any reasonably moist fertile soil. Protect from slugs and snails, especially early in the season. Remove dead leaves and flower stems when they die back in winter.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
