The Annual Delphinium or Larkspur is a quick-growing plant with varieties suitable for both the back and front of the annual border. The upright flowering spikes bear densely-packed blooms in white, pink, red or blue. The foliage is feathery and the flower-heads are popular for indoor arrangements. Stake tall varieties and remove dead blooms.

VARIETIES: The D. consolida group contains the stately ‘Giant Imperial’ varieties (4 ft) which produce tall spikes of Stock-like flowers. The D. ajacis group produces varieties which are rather shorter and earlier flowering – these so-called Hyacinth-flowering types include ‘Tall Rocket’ (2.5 ft) and ‘Dwarf Rocket’ (1 ft). Remember that the seeds of Delphinium are poisonous.

SITE AND SOIL: Any well-drained garden soil will do – thrives in sun or light shade.

PLANT DETAILS: Height 1-4 ft.

Spacing: 1.5 ft.

Flowering period: June-August.

PROPAGATION: Dislikes root disturbance. For best results sow seeds in September – alternatively sow in March.
