To be honest, tall larkspur (Delphinium exaltatum) is no substitute for the dramatic, towering spires of hybrid delphiniums. But if you’re looking for an elegant and dependable perennial for your mid- to late summer garden, this native species is definitely worth considering. Tall larkspur usually reaches 4 to 5 feet in height (maybe 6 once well established) and typically flowers in a range of purple-blue tints and shades in mid- to late summer: in perfect time to pair with rattlesnake master (Eryngium yuccifolium) and cardinal flower (Lobelia cardinalis), among other perennials. These seeds may also produce some pinkish flowered plants, as you can see in the photos here. Bees and hummingbirds are frequent visitors to the spurred blossoms. Like common garden delphiniums, this species is toxic to people and animals if eaten. Native to parts of the north-central and eastern US. Full sun to partial shade; average to moist but well-drained soil. Perennial; Zones 4 to 7 (maybe 8 with afternoon shade).
