Delphinium exaltatum, commonly known as Tall Larkspur, is a perennial herb that is native to the eastern United States, particularly in the Appalachian and Ozark Mountains, as well as in prairies and glades of the central states. It can grow up to 6.6 feet tall and typically blooms between July and September, showcasing spikes of vibrant, deep blue to purple or occasionally white flowers that are highly attractive to pollinators. The flowers are considered showy due to their size and the contrast of their colors against the green foliage.

Tall Larkspur is valued for its vertical accent and striking floral display in wildflower gardens, meadows, and naturalized areas. It prefers partial shade to full sun and requires well-drained soils, especially those that are rich in lime (calcareous). While it is toxic to livestock due to the presence of alkaloids, it is an important nectar source for butterflies and hummingbirds. In cultivation, it is important to protect this plant from strong winds and to provide support for the tall flower spikes. Overly wet soils and high humidity can lead to fungal diseases, which are potential problems for this species. Tall Larkspur is not typically invasive but can be affected by habitat loss and changes in fire regimes in its native range.CC BY-SA 4.0
