Diamonds Blue Delphinium feature clumps of semi-double flower blooms in vibrant clear blue with small white stamens in the center blanketing rich green foliage spikes. The Delphinium performs best in areas that receive full sun in any combination planter, bordering a garden flower bed or in a cut flower bouquet. Low maintenance.
Plant in well-drained soil. Water regularly. Keep soil surface moist but not soggy. Fertilize once or twice a week. Remove faded or dead flowers to prolong blooming all the way into fall.
