Columbine Blue Star Aquilegia Caerulea is a hardy perennial plant native to North America. Columbine Blue Star seeds germinate fast, and this Columbine plant is one of the most beautiful Columbines that features large, 4 inch, deep-blue flowers with white corollas. The showy, scented flowers appear all spring long and attract hummingbirds, bees and butterflies.
Columbine Blue Star is often grown in hummingbird or cut flower gardens, and Columbine is excellent as a border or accent plant for rock and alpine landscapes. Aquilegia Caerulea seeds have to be kept moist until germination, and Columbine grows best in full sun or partial shade in hot climates preferring rich, moist soil, but this perennial flower is very adaptable to less than perfect soil conditions.
