Delphinium elatum 'Million Dollar Sky'

Larkspur

This new Delphinium is the perfect match to 'Million Dollar Blush' and 'Million Dollar Blue', offering a shorter option for Hybrid Bee Delphiniums. Large spikes of semi-double to double light blue flowers with a white bee have very erect stems. Strong stems carry the unusually large blossoms above the dark green, deeply dissected foliage in early summer and then again in late summer or early fall. 'Million Dollar Sky' is very heat tolerant as well as being cold hardy to zone 3.

Our products are available for retail purchase only. Please call for availability as stock levels fluctuate throughout the season. We are unable to ship plants or other products.

Larkspur Growing and Maintenance Tips

Delphiniums thrive in the cooler climates of the north country, though they will grow as far south as zone 7. They grow best in rich, well-drained soil with a basic pH. If your soil is naturally acidic, adding lime will help to provide these conditions. They are also heavy feeders. The addition of compost or manure to the soil as well the use of granular fertilizer will result in healthier, stronger plants.

Delphiniums can be grown in full sun or partial shade, though full sun may help to prevent powdery mildew. When planting, be sure to set the crown at or above soil level to avoid rot. Since their stems are hollow, taller varieties of Delphiniums should be staked to prevent damage from wind and rain. These new hybrids tend to be longer lived than their short-lived cousins but may be propagated from basal cuttings.
