Delphinium Cultorum Black Knight - is a large perennial from the Pacific Giant Hybrids. It may require staking while flowering especially in windy areas as this plant can grow up to 6 feet tall. Delphinium 'Black Knight' has tall spikes of flowers in a gorgeous shade of dark violet-blue with a black bee in the center. Sow Delphinium seeds to produce this gorgeous addition to the perennial flower garden. Hummingbirds and bees will visit often! Plant Delphinium Black Knight in full sun in compost rich well drained soil. Delphinium Cultorum care includes applying a balanced liquid fertilizer every month as Delphinium plants are heavy feeders. Delphinium plants should be replaced every 3 to 4 years as they will become woody and begin to decline with age. Cut plants back after initial flowering for a possible second showing in fall. Delphinium flowers are excellent for cutting. This flower seed produces Delphiniums that will grow at elevations up to 10,000 feet which is very rare.
