Annual. Formerly known as Delphinium consolida. Delphinium-like long-stemmed flower spikes are used as cutflowers or in dried arrangements. Upright 3-4' tall plants. The Giant Imperial series features long racemes of double flowers.
Culture: Likes cool moist conditions. Very slow to give in to fall frosts. May be direct seeded in early spring or started indoors and grown on at 55° and set out in 8 weeks. Does not germinate well in warmer temperatures. Refrigerating for a week improves germination. Cut when one third of the flowers on the stem are open. For cuts, vase life is 6–8 days. Excellent for drying. Self-sows readily.
All flower seeds are open-pollinated except where noted.
Days in parentheses after a variety indicate days to first bloom.
Almost all the flowers we list are open- pollinated and easy to save seed from. Some types cross readily, but who cares! Save the seeds, plant them, and be surprised.
These flowers are especially easy to save seed from: bachelor’s buttons, calendula, cerinthe, cosmos, love-in-a- mist (nigella), nasturtium, poppy, strawflower, sunflower, sweet pea and tithonia.
