Delphinium Black Knight (Larkspur) | Two Live Perennial Plants | Non-GMO, Large Flower Spikes that Bloom All Summer

This garden stunner is a must-have for cut flowers and pollinators. Delphinium Black Knight (Larkspur) is perennial in zones 3 to 9 and will grow to nearly 6’ tall! Each flower spike is packed with dark purple-blue flowers with a light interior (which is a beacon to bees and butterflies).

Prized for its beautiful cut flowers, Delphinium is a classic English Garden flower and will bloom for most of the summer. The large upright stalks make the perfect backdrop for shorter flowering perennials. Combine with other favorites such as Shasta Daisy or Moonbeam Coreopsis.

This plant needs full sun and moist, but well-drained soil with lots of organic matter. Their roots like to be cool so mulching after planting will help them. Delphinium also does not like humidity so space at least 24” apart so they get air flow on muggy days. Plant will benefit from support (such as a fence or flower stakes) as tall flower spikes can be damaged by wind. Deadhead spent flower stalks to encourage more blossoms.

Note: all parts of this plant are toxic to humans and pets.
