Delphiniums are a wonderful perennial that produce tall, stately flower spikes in a range of colors from white to blue to pink or rose. They are worth the effort to grow because they are so beautiful, and are treasured by both home gardeners and professional cut flower growers. Delphiniums are hardy perennials but do not care much for severely hot summers. Plants will flower the first year from sowing and will bloom in early to mid-summer. They are also known to produce a second set of flower spikes later in the season if the first set is cut soon after blooming.

Cut flower growers can space these plants quite closely (4-6” apart), and it is recommended that some type of support be given to the flower spikes (staking or netting) so that they do not bend over or break under high winds. Note the Delphiniums are considered a short-lived perennial and will need to be replaced after 2-3 seasons.
