Botanical Name

DELPHINIUM 'Summer Nights'( SUMMER SERIES)

Plant Common Name

Delphinium, Larkspur, Summer Nights Delphinium

General Description

The compact, bushy habit and long bloom time of ‘Summer Nights’ makes this delphinium an especially desirable garden perennial. In summer it produces many loose flower spikes covered with spurred, five-petaled flowers of dark indigo blue. These are sturdy and well branched, so unlike other delphiniums, they do not require staking. Deadhead plants regularly to promote continued flowering.

These plants perform best in full sun, evenly moist soil and appreciate regular fertilization. They do not appreciate areas with markedly hot and humid summers and will wane in the heat. Members of the Summer Series are short-lived perennials and tend to lose their vigor after two to three years. Plant them in cottage gardens, sunny borders and large containers. Their flowers are very attractive to bees and butterflies and are great for cutting.
