Delphinium grandiflorum 'Summer Morning'
Butterfly IconDeer Resistant IconHummingbird Icon

Plant Type: Perennials

Totally unlike the tall, spiky Delphinium cultivars, this little beauty stands at a height of 10"-12" and forms compact mounds of well-branched foliage. It puts on a spectacular show from early summer to fall, with romantic light pink flowers which cover the lacy leaves. Though it is short-lived, it is worth using as edging, a bedding plant, or in containers combined with pastel colored annuals.

Growing & Maintenance Tips:

Delphiniums thrive in the cooler climates of the north country, though they will grow as far south as zone 7. 'Summer Morning', however, has demonstrated better heat tolerance than some other cultivars. 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. These perennials tend to be short-lived and often start to lose their vigor after 2-3 years. Expect to replant them every few years or propagate new plants from basal cuttings of the original specimens. 'Summer Morning' may self-seed, particularly in cool-summer regions.
