Delphinium exaltatum
Tall larkspur
Wow! A blue-flowered Delphinium for bright to average shade and it is native to the woodland glades from Alabama to Pennsylvania. Ours came to us thanks to the generosity of the Holden Arboretum in Kirtland, Ohio. Spikes of spurred blue flowers top 3-6' stems from July to September. A welcome addition to the woodland edge or bright shade border.

Interesting Notes
Tall Larkspur has grayish green leaves divided into 5 lobes that are in turn divided into 3 teeth at their tips. It is a large and vigorous plant. It blooms fairly late so the foliage remains in good condition most of the summer. William Cullina, Growing and Propagating Wildflowers

Growing and Maintenance Tips
Grow in partial to full shade in rich soil with high organic content. Seeds in freely when happy. Prefers average to rich soils with good drainage and is quite drought tolerant once established. Not one for clay!
