Delphinium exaltatum - TALL LARKSPUR

"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." - Mt. Cuba Center

The flowers are usually blue, purplish, or lavender-pink. Deer and rabbit resistant; the entire plant is highly toxic to humans, dogs, cats, and livestock. It performs best in cooler climates, but is more tolerant to the heat of the south than many other delphiniums. Can reach up to 6,' so it's best to plant it with other taller perennials that can support its slender stems, and choose places for it that are protected from strong winds.

Use it in flower beds, cottage gardens, prairie plantings, hummingbird gardens, butterfly or pollinator gardens.
