Helping You Become a More Successful Gardener
DELPHINIUM( Belladonna Group)
Delphiniums in the Belladonna Group are highly regarded for their tall, airy, branched spikes of flowers which bloom in numerous shades of blue and white. These hybrids were developed through extensive breeding of various species native to Asia and North America. Their spurred, five-petaled blossoms are borne on slender, branched stems from early to late summer. Somewhat resembling “elf caps”, the showy blooms are also attractive to bees and butterflies. They rise from basal clumps of lush green, deeply lobed foliage which has an almost feathery appearance.
Grow delphiniums in full sun and fertile, well-drained soil which receives regular moisture. Slightly alkaline soils are ideal. The tall flowering stems may require staking to prevent toppling, and windy sites should be avoided. After the flowers fade, promptly cut back the stems to any lower flowering side shoots to encourage extended blooming. The plants may produce a second full show of flowers by mid-autumn. Monitor closely for slugs and snails in spring, as these can damage new growth.
Tall delphiniums bring dramatic vertical appeal and gorgeous color to the perennial border or cottage garden. Their striking blooms are also highly prized as cut flowers. Often short-lived, these perennials are frequently treated as annuals or biennials, particularly in areas with long, hot summers.
