Delphinium delavayi

Delphinium delavayi

Delphinium delavayi

Family ranunculaceae
Life cycle perennial
Flowers blue (June)
Size 2-3'
Light sun-part shade
Seed ripensmid-July

Chinese species of perennial larkspur. Flowers are a vivid blue and hairy (especially obvious on the buds), with prominent bees. The whole flower looks like Dr. Seuss might have designed it, especially the crumply-curvy back end. Each is attached to the flower stem in alternating fashion; the overall effect packs a visual punch. Growth habit is upright, about mid-way in height between the taller hybrids and dwarf varieties. Black crinkly seeds.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
