Family

Ranunculaceae

Botanical Name

DELPHINIUM 'Pure White'

Plant Common Name

Delphinium, Larkspur, Pure White Delphinium

General Description

Delphinium ‘Pure White’ lends elegance to the summer garden with its heaven-reaching spires of crisp white, semi-double flowers. The pristine blooms are borne densely on tall spikes from early to midsummer, and sometimes feature a small green “bee”, or central tuft of stamens. They rise above mounds of rich green, deeply lobed foliage, and are visited by butterflies, bees and hummingbirds.

Delphiniums prefer full sun and moist, fertile, well-drained, slightly alkaline soil. Thriving in areas with cool to moderate summer weather, they falter when exposed to very hot temperatures. Taller varieties may require staking to avoid toppling, and windy sites should be avoided. After the flowers fade, promptly cut back the stems to encourage a possible second show of flowers in autumn. Monitor closely for slugs and snails in spring, as these can damage new growth.

The beautiful colors and striking vertical habit of delphiniums add drama to mixed beds and borders. Their gorgeous blooms also make outstanding cut flowers. Often short-lived, these perennials are frequently treated as annuals or biennials, particularly in areas with long, hot summers.
