-
The Greek work 'delphinium' translates to dolphin. The dolphin-like shape of this plants buds has earned its Latin name.
Carolina larkspur is a south-eastern native perennial wildflower in the Ranunculaceae family. It can be found growing on rocky, limestone glades. Its preferred location will include dry alkaline soil in full sun. Not being heat tolerant, it may disappear as the temperatures climb and reappear as the temperatures cool.
The blue flowers make this plant a favorite of bumblebees. As a species, bumblebees are more adapted to visually see blue, ultraviolet and yellow wavelengths. The coloring of the Blue Larkspur is a bumblebee magnet.
The flowers appear on a raceme with up to 30 to 40 flowers. They bloom over a 3 to 4-week period in late spring to early summer. The plant will then become dormant. Do to the long raceme, this plant may need to be staked.
Considered a short-lived perennial, it does however, reseed itself.
Insects, Diseases, and Other Plant Problems: Crown rot, botrytis blight, leaf spot and powdery mildew are diseases to watch out for. Aphids, mites, stem borers, leaf miners, snails and slugs are insects that can damage your plant.
This plant does not transplant well.
