Delphinium exaltatum is native to Eastern North America from Pennsylvania and Ohio south through the Appalachians into northern Alabama, with several small, isolated populations existing in the Ozarks in far south-central Missouri. Tall larkspur typically grows 4-6′ tall and features loose terminal racemes of gentian blue flowers which bloom in summer. Individual flowers (to 1″ long) are complex and asymmetrical and feature five sepals, one of which is spurred into a distinctive prong resulting in the common name. It has divided, 3-5 lobed, deep green leaves. This species is taller, blooms later and has more abundant foliage than most other native U.S. larkspurs. As is the case with many of the buttercup family members, all parts of this plant are poisonous.
