DELPHINIUM Dark Black Knight Seeds

Inc. GST + FREE Shipping

Delphinium Dark Black Knight is a modern hybrid variety of delphinium specifically bred to produce spectacularly dark-purple flower spikes, definitely the darkest Delphinium variety ever grown by The Climbing Fig. Delphinium Dark Black Knight is a large cultivar variety which means that it will grow to about 1.5m to the top of the flower spikes. Delphinium Dark Black Knight is a flowering annual that will generally first flower in Spring and produce an even more spectacular crop of flowers through to early Summer and even into Autumn if they are not in a frost prone area. At The Climbing Fig we stock a range of Delphinium varieties, including the famed Delphinium Belladonna, as well as the related Larkspur varieties, Larkspur Cannes Deep Pink and Larkspur Imperial Giants Mix.
