Crystal Star Columbine (Aquilegia caerulea) is an elegant perennial prized for its exceptionally large, pure white flowers accented by long, graceful spurs that give each bloom the appearance of a delicate star. This refined selection of the Rocky Mountain Columbine offers a fresh, luminous display from late spring into early summer, bringing beauty to woodland gardens, perennial borders, and cottage landscapes. The intricate blossoms seem to float above attractive blue-green fern-like foliage while attracting hummingbirds, butterflies, and early-season pollinators.
Garden Uses
Crystal Star Columbine is an outstanding choice for woodland gardens, perennial borders, cottage gardens, shade gardens, pollinator gardens, and naturalized landscapes. The crisp white flowers brighten partially shaded areas and combine beautifully with hostas, bleeding hearts, ferns, foxgloves, coral bells, woodland phlox, Virginia bluebells, and spring-flowering bulbs. It is equally at home in alpine gardens and makes an excellent cut flower for delicate spring bouquets.
Growing Information
Crystal Star grows best in full sun in cooler climates or partial shade where summers are warm. It prefers fertile, humus-rich, well-drained soil that remains evenly moist but never waterlogged. Plants typically mature 24 to 30 inches tall with a spread of 15 to 18 inches, forming attractive clumps of finely divided foliage. Remove spent flowers to encourage a tidy appearance, or allow a few seed heads to mature if natural reseeding is desired. Columbines often self-sow gently without becoming invasive, creating attractive colonies over time. Seeds benefit from a period of cool stratification and should be lightly covered with soil.
