Belladonna Delphinium is suitable for zones 3-7 and is a tender perennial usually lasting only three years. These do not require cold treatment but it is recommended you start in pots over winter and transplant in spring after your last frost. These delphinium require light to germinate so sow on the surface on your pot and lightly dust with vermiculite or sand. These are slow growing and while they will flower slightly in their first year they flower profusely in years 2-3 throughout the spring and summer.
These Delphinium do not require a cold treatment to germinate, but if you have time to cold treat them your germination rate will be higher. If cold treating mix your packet of seeds with 1/4 cup of moist sand and store inside a baggie in your refrigerator (not freezer) for 30 days and then sow as above.
We find that here in hot and humid zone 7 it helps to lift them in late fall of year two, re work your garden bed, and then replant them. After year three they will stop flowering and eventually die off.
