Summary
Delphinium exaltatum is an attractive and floriferous native woodland-edge perennial that is equally at home in the home garden border. Growing to a height of 4’, this summer-blooming perennial has attractive medium-green, palmate leaves and narrow stalks of showy, deep blue-purple flowers that attract hummingbirds and butterflies. Tall larkspur excels in moisture-retentive, well-drained, humus-rich, slightly alkaline soil and prefers filtered shade to full sun. Delphinium exaltatum is an attractive addition to the garden when planted en masse with Coreopsis tripteris, Solidago rugosa ‘Fireworks’, Vernonia angustifolia, Silphium simpsonii, and Veronicastrum virginicum.
