Botanical Name

DELPHINIUM 'Pennant White'( PENNANT SERIES)

Plant Common Name

Delphinium, Pennant White Delphinium

General Description

The snowy, semi-double flowers of delphinium ‘Pennant White’ are borne on compact stemsw which do not require staking as do those of taller varieties. They appear atop mounds of deeply lobed, rich green foliage from late spring to midsummer, and may be visited by butterflies and bees.

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 possible reblooming. 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.
