Delphinium carolinianum

Common Name: Carolina Larkspur

Carolina Larkspur is a tall, upright perennial growing 1 to 3 feet in height, with striking spikes of blue to violet flowers blooming from late spring to early summer. It prefers well-drained soils and is commonly found in dry prairies, savannas, and open woodlands. The plant provides nectar for pollinators, particularly bees and butterflies, but is toxic to livestock if ingested. Carolina Larkspur adds vertical interest to native plant gardens, prairie restorations, and pollinator-friendly landscapes.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
