Description

Aquilegia 'Sunshine' is a very attractive hybrid variety that forms gorgeous, large, bright yellow fully double blooms with long spurs from late spring to mid-summer. This hardy and easy to grow perennial has a bushy habit and attractive bluish-green foliage. Although it is rather short-lived, it self-seeds abundantly in cool, well-drained soil, preferably in part shade.

Aquilegia 'Sunshine' is a hybrid variety selected from the Blue Columbine, the Colorado state flower (Aquilegia caerulea). This North American species belongs to the Buttercup or Ranunculaceae family and can be found growing wild throughout the Rocky Mountains. 'Sunshine' forms a compact, upright clump that grows to a height of about 60 cm in full bloom, for a width of 30 cm. For 4-6 weeks from June to July, large flowers emerge at the tip of sturdy stems. They measure 5-7 cm in diameter, with a double corolla and long horned spurs. They display two harmonious tones of yellow: bright, soft pastel yellow and creamy, pale yellow. The bluish-green leaves have a lacy, delicate clover-like appearance. Aquilegias are short-lived perennials; flowering generally reaches its peak after 2 or 3 years of cultivation. Although they self-seed easily, they are not always true to type when different varieties of columbine are grown in close proximity.

Columbines or Granny's Bonnets have been popular ornamental garden plants since the Middle Ages. They will fit in just about anywhere, bringing a discreet lightness and fantasy to mixed borders and perennial beds; they are ideal for underplanting shrubs and trees, growing up slopes or decorating shady rock gardens. They are excellent cut flowers. In old-fashioned cottage style gardens, columbines combine well with perennials such as foxgloves, bellflowers, wood cranesbill, bleeding hearts or lady’s mantle.

Planting and care

Sow from spring to midsummer in light, free-draining sowing mix and cover lightly. Germination can take 1 to 3 months at 15-21°C. To speed up the process, place the seed trays in a polyethylene bag and leave them in the refrigerator for 3 weeks. Check on them regularly and take them out of the refrigerator once they start to germinate, moving them to a warmer place (15 to 21 °C). When they are strong enough to be handled, transplant them into small pots. Place them in a cold frame and plant out their final locations in autumn.

Aquilegia caerulea likes moist, rich, free-draining soils and prefers part shade or dappled sunlight in the afternoon. It adapts well to limestone. Although it is very disease-resistant, it is often subject to to attacks by aphids, caterpillars, slugs and snails. Since columbines self-seed easily, it is possible to let several flower stems go to seed after flowering. However, we recommend only doing this on strong, vigorous plants as this exhausts the plants prematurely, thus diminishing their already short lifespan (3 to 4 years).
