Summary
Tall larkspur (Delphinium exaltatum) is an attractive and floriferous native woodland-edge perennial that is equally intriguing 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. Tall larkspur is an attractive addition to the garden when planted en masse with tall tickseed (Coreopsis tripteris), Fireworks wrinkle-leaf goldenrod (Solidago rugosa ‘Fireworks’), tall ironweed (Vernonia angustifolia), Simpson’s rosinweed (Silphium simpsonii), and Culver’s-root (Veronicastrum virginicum). Zones 5-7.
