Delphinium is a genus of wonderful annuals and perennials known for their colorful and attractive flowers that grow abundantly on long stalks. Native to temperate regions of the northern hemisphere, Delphinium are easy to grow and manage. Most species grow tall with stalks full of flowers though some low-growing species are also available. Taller species are prefect for growing in the background of flower beds or landscape.
Delphinium is know traditionally for its showy flowers of strong blue or purple color, however a large number of hybridized Delphiniums have also been produced in recent years. The hybridized Delphinium produce flowers in all shades of white, blue, mauve, red and yellow.
Popular in traditional gardens, Delphinium has been extensively hybridized to produce long-lasting cut flowers. Some popular hybrids of Delphinium include: ‘Atlantis’, ‘Blue Dawn’, ‘Elizabeth Cook’, ‘Oliver’, ‘Summerfield Miranda’, and ‘Sungleam’.
Delphinium requires fertile and slightly soil but well-drained soil under the bright sun. The plants can be propagated from seeds as well as divisions. The flower stalks should be provided firm support of staking when the stalks reach 10 inches or more. Delphiniums can be cut back to the ground after the end of flowering season in order to encourage better growth for the next flowering season.
