AQUILEGIA. Columbine. Widespread, mostly in north-temperate regions. These are graceful, long-lived perennials for moist spots in the garden. They make compact clumps of seasonal shoots from a branched rootstock. Their usually long-stalked, fern-like leaves, elegant by themselves, form a beautiful foil for branched clusters of large, usually nodding blossoms in spring. Each flower has five colored, usually spreading sepals and five inner petals whose base is drawn out into a nectar-bearing spur. They are fine plants for butterflies and other insects, and the red-flowered ones will draw hummingbirds from far and wide. I have had great fun selecting and hybridizing among the new forms which continually pop up at the nursery; may gardeners find them similarly enchanting. Winter deciduous. Sun or part shade, reasonably well drained soil, constant moisture during active growth. Those listed are hardy to below 0o, except as noted.
formosa. Western columbine. A Western native with bluish green, finely divided leaves and 2-3' stems of red and yellow flowers. Ours are from exceptionally large flowered stock, originally encountered along the Van Duzen River in northern California. 10oF or less.
