Prized by gardeners, Delphinium Astolat Group (Candle Larkspur) are tall perennials with sturdy flower spikes, densely packed with large, satiny, semi-double, lavender-pink flowers with dark eyes. Blooming for weeks from early to midsummer, these Pacific Giant hybrids add a wonderful architectural presence in the garden and draw attention from quite a distance. Rising from a low mound of deeply-cut green leaves, they have a neat compact habit. Splendid in cottage gardens.

  • Attractive to hummingbirds and butterflies, but ignored by deer and rabbits!
  • A welcomed addition to beds and borders, cottage gardens. For the best visual impact, plant your Delphiniums in groups. Excellent as cut flowers, they deserve a spot in your cutting garden.
