Answer: Your delphiniums should bloom the first year from seed, probably from mid-summer through autumn. Snip back the spent flower stalks and you may get a second flush of slightly smaller blooms. If you allow the flowers to remain they will probably develop seeds, which you can harvest to plant next year, or allow to spill on the ground around the plant to encourage new plants the following year. It's a process called self-sowing and is recommended because delphiniums are relatively short-lived perennials. Enjoy!
