Delphinium 'Guardian White' (Candle Larkspur)

Delphinium elatum 'Guardian White', Guardian Series


Prized by florists, Delphinium 'Guardian White' is a mid-sized herbaceous perennial with sturdy flower spikes, densely packed with double, glistening white flowers. Blooming for weeks from early to mid summer, it adds height and majesty to the garden and draws the attention from quite a distance. Rising from a mound of divided, rich green foliage, this Delphinium has a neat compact habit. This vigorous hybrid belongs to the Guardian Series, which were bred for their uniform flowers and early blooming habit. Exceptional cut flower.

  • Grows up to 30-39 in. tall (75-98 cm) and 10-12 in. wide (25-30 cm).
  • Performs best in full sun or part shade in fertile, medium moisture, well-drained soils. Provide a sheltered location to protect your plants from strong winds.
  • Attractive to hummingbirds and butterflies, but ignored by deer and rabbits!
  • Welcomed addition to beds and borders, cottage gardens. For best visual impact, plant your Delphiniums in groups. Excellent as cut flowers, they deserve a spot in your cutting garden.
  • Removing spent flower spikes will promote another round of blooms in late summer or fall.
  • All parts of the plant may cause severe discomfort if ingested.
