Delphinium Black Knight are extremely tall, graceful spikes of deep midnight blue with dark bees. Their leaf mound is domed in early spring and elongates as the flower spikes rise. If the main flower stalks are removed as flowers begin to fade, a secondary set of blooms can be produced in late summer or early fall. Delphiniums are popular in cottage-style gardens and cutting gardens. This variety will do best if staked to support the tall, heavy flower spikes, especially in windy areas.
In hot, humid regions plants do not usually last more than 2 to 3 years and can be attacked by mildew in mid summer. If this occurs, cut the effected growth back to encourage fresh foliage growth. A high phosphorous fertilizer in early spring is recommended. Water plants during the summer if rainfall amounts to less than an inch per week.
Sowing: Direct sow in the spring, Summer and Autumn. Start indoors in the Winter for spring planting.
Mix 2-4 inches of compost into the soil. Delphiniums are difficult to grow from seed, but not impossible! Germination can be aided by placing seeds on a moistened paper towel, folding it to fit into a zip seal bag and refrigerate for a week or two. Sow the seeds directly into the prepared seed bed immediately after removing from refrigeration and keep the soil moist until germination.
Place the seed, covering with 1/4 inch of seedling mix and moisten. Keep moist, but not soggy to prevent fungal infections.
Watch for germination 10-20 days after sowing.
Once the second pair of true leaves emerge, it's time to transplant into individual pots if started indoors.
If started indoors, transplant after a feeding of 12-12-12 fertilizer and hardening off for a week.
Delphiniums can be divided in the spring. Remove and replant new growth plants on the outer periphery of the plant and then discard the heart (hard center of the plant).
These are seeds from my own garden plants. They were lovingly raised from seeds themselves.
