Flowers are borne in pairs, drooping from leafless stems arching above the foliage. Self-sows when happy and enjoys part to full shade in humus-rich, woodland soil. 4 & T2

Scientific Name (Genus/Species): Aquilegia vulgaris Mix
Family: (Ranunculaceae)
(P) to 3′. Columbine. Europe. The common name Columbine is derived from the Latin word for “dove” in reference to the resemblance of the inverted flower to five doves clustered together – a most descriptive image indeed. The intricate flowers can be nodding or horizontal and consist of five sepals and five petals to 1-½ inches long and come in a wide variety of colours, often developing dorsal hooked spurs. Interesting five, fused seed follicles follow. Each follicle has a long thin beak and holds many small, shiny, black seeds and persists until fall. The bushy, clump-forming plants have branched, thinly hairy stems and pinnate leaves, with the basal leaflets trifoliate. One of the most beloved plants appearing in an array of colours, sizes and forms, thanks to natural hybridization in the garden. In 2025 we collected seed from the colours below. Sun to part shade. 4 & T2
