Magnify glass

Brunnera macrophyllaJack Frost


Siberian Bugloss

Perfect for a shady spot

Superb drifted through a woodland garden, but a delightful plant for any lightly shaded spot when in early spring the sky blue, forget-me-not flowers rise in airy sprays above silver frosted, heart-shaped leaves.


Perfect as a ground cover for edging a border or a woodland path, and lighting up a shaded spot.


It loves a rich, fertile and moist soil. Remove any stems with green leaves that do not show the silvering that makes this plant so attractive.

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.
