Dwarf larkspur is a herbaceous perennial in the buttercup family native to the eastern United States, where it is the most common Delphinium found in moist forests and thickets. This plant will struggle in areas with high humidity summers.
The flowers bloom in July to Sept. in loose clusters of 6-12 flowers that are usually bluish-purple but sometimes have some white. They are tubular with one sepal bent backwards to create a spur. The leaves are finely cut into deep lobes and mostly basal.
Dwarf Larkspur prefers fertile moist soils with some shade in the afternoon and a protective spot from winds. Use in borders, mass planting or small groups, a woodland setting or native garden.
Diseases, Insects and Problems: Diseases are powdery mildew, botrytis blight, leaf spots and crown rot. Insects are Slugs and snails, aphids, leaf miners, stem borers and mites. Staking may be required for taller plants. Poisonous.
