#ProPlantTips for Care:
Dwarf Delphinium are blissfully low-maintenance. These modern perennials boast strong stiff stems that rarely require staking if planted in a sheltered spot. Plant in the full sun for the strongest growth and in well-drained organically enriched soils. Provide regular yet moderate moisture throughout the growing season and add a 3-4 inch layer of mulch over the root zone for moisture retention and insulation. Encourage reblooming by trimming down the flowers as they near finishing. You'll enjoy another excellent display in late summer and fall if those first flowers are removed. In late fall, prune back the mound and water in well for the winter.
