Western Columbine (Aquilegia formosa) is a stunning, short-lived perennial that ranges from Alaska to California. It can be found in a variety of habitats, including montane meadows, open woodlands, and along streams or rocky slopes. The uniquely intricate flowers, a hallmark of the Aquilegia genus, feature deep scarlet to orange sepals and yellow petals, creating a striking color combination. The nodding flowers are complemented by attractively lobed, blue-green foliage with tinges of reddish purple.
Western Columbine typically blooms from late spring to early summer, with the peak flowering period occurring in May and June. The delicate, pendulous flowers hang from tall stems, swaying gently in the breeze. The blooms provide a valuable nectar source for hummingbirds, with the flower shape and coloration being specifically adapted for pollination by hummingbirds and bumblebees. Additionally, the seeds are consumed by some birds.
Western Columbine prefers well-drained soils with varying fertility. It can tolerate a wide range of soil types, including sandy or rocky soils. To germinate, the seeds of Western Columbine require a period of cold stratification. Sow the seeds in fall or late winter, lightly covering with soil. Once established, the plant is relatively low-maintenance and can self-seed to create beautiful colonies over time.
