Delphinium Larkspur

DelphiniumLarkspur

Ranunculaceae

Strong perennial for pots and borders, suitable for cut flower production. Early spring sowings will produce late summer flowering the first year. Autumn sowings and overwintering in greenhouse will result in sturdier habit. For glasshouse cut flower production, use annuals or biennials. Dependent on the temperatures these plants can produce flowers up to three times a year. Gather when 1/3 of the flowers are open.
