Delphinium grandiflorum 'Summer Nights'

Delphinium

Deep blue flowers, some with a blush of purple, are borne on well-branched plants. This Delphinium is a dwarf form that performs better in our heat and humidity. It is very long blooming and has proven itself to be an excellent performer.

Prefer morning sun with afternoon shade and moist, well-drained, humus-rich, neutral to alkaline soil. This is a good variety for warm climates.
