Columbine is an old-fashioned perennial with dainty, spurred flowers in shades of pink, yellow, blue, red or white. It flowers from late spring to mid summer and has delicate, light grey to grey-green foliage. The dwarf species look charming in a rock garden and the taller species are suitable for borders.

Aquilegia flabellata var. pumila grows up to 25cm (10iti) tall and produces white to violet-blue flowers from late spring to mid summer. Var.

Alternatively, divide and replant immediately from mid autumn to early spring.

Pests and diseases: Leaf miners may burrow into the leaves. Aphids can leave the stems sticky and sooty.
