General Culture:
Easily grown in average, medium, well-drained soil in full sun to part shade. Tolerates wide range of soils except heavy, poorly drained ones. Prefers rich, moist soils with light to moderate shade. Remove flowering stems after bloom to encourage additional bloom. Keep soils uniformly moist after bloom to prolong attractive foliage appearance. When foliage depreciates, plants may be cut to the ground. This cultivar reportedly may be grown from seed and may self-seed in the garden under optimum growing conditions. However, different varieties of columbine may cross-pollinate in the garden producing seed that is at variance with either or both parents.
Noteworthy Characteristics:
'Silver Edge' is a compact columbine noted for its striking foliage which is green variegated with white/silver streaking and white/silver margins. It is a bushy, clump-forming perennial that typically grows 9-15" tall and features short-spurred (incurved), nodding, light to sky blue flowers with white at the petal tips. Blooms in spring. Biternate to triternate, almost fern-like foliage shape (but not color) is somewhat suggestive of meadow rue (Thalictrum). Leaflets of plants of this species are rounded and fan-shaped thus giving rise to the common name of dwarf fan columbine. Aquilegia comes from the Latin word for eagle in reference to the flower's five spurs which purportedly resemble an eagle's talon.

Susceptible to leaf miner. Foliage usually declines by mid-summer at which point it should be cut to the ground.
Uses:
Compact shape makes this one of the better columbines for rock gardens. Also good in borders, cottage gardens, open shade gardens or naturalized areas. Continue to water plants after bloom to enjoy the ground cover effect of the attractive variegated foliage.
