Aquilegia longissima A. Gray
Longspur columbine, Longspur yellow columbine
Ranunculaceae (Buttercup Family)
USDA Symbol: AQLO
A yellow-flowered Southwestern columbine 1-3 feet tall. Flowers somewhat pale yellow but with dramatically long spurs 10-15 cm long. Petal blades are 15-30 mm in length. Leaflets to 4 cm long, carried on 30 cm petioles. Native to moist canyons from southern Arizona and the Chisos and Davis Mountains of west Texas, south into mountains of adjacent northern Mexico.
This is one of the most striking of the popular Southwestern yellow columbines, owing to its very long flower spurs. Its flowers tend to be a paler yellow than those of Aquilegia chrysantha, but vary in intensity. Like other Southwestern yellow columbines, it requires adequate shade, sufficient moisture, and well-drained soil.
The genus name Aquilegia comes from the Latin aquila which means eagle and refers to the spurred petals that many believe resemble an eagles talons.
