Consolida ajacis

Larkspur, Annual Delphinum
Ranunculaceae
Annuals

Native to southern Europe. Upright plants grow to 1–5 ft. tall and 1 ft. wide, with deeply cut, almost ferny leaves. Blossom spikes are densely set with 1–1 1/2-in.-wide flowers (most are double) in white or shades of blue, lilac, pink, rose, salmon, or carmine; there are also blue-and-white bicolors. Best bloom comes in cooler spring and early summer months. Giant Imperial strain has many 4-ft., compactly placed vertical stalks. Regal strain has 4-ft. base-branching stems and thick spikes of large flowers similar to perennial delphiniums. Super Imperial strain is base branching and has large flowers in 1 1/2-ft. cone-shaped spikes.

Sow seeds and lightly rake in. Fall planting is best except in heavy, slow-draining soils. Thin plants to avoid crowding and to get the biggest flowers. Nursery transplants are also available for early-spring planting.
