The common name larkspur is shared between perennial Delphinium species and annual species of the genus Consolida. [3] Molecular data show that Consolida, as well as another segregate genus, Aconitella, are both embedded in Delphinium. [4]
Perennial delphiniums are renowned for their rich colours and commanding presence. They flower in early summer and are perfect for beds and borders and make a glorious cut flower. Easy to grow annual delphiniums (consolida or larkspur) are smaller and will flower all summer.

However, they don’t like to be waterlogged, so make sure the soil drains well.Wind: Delphiniums benefit from shelter from strong winds, as their tall spikes can be easily damaged.The timing of planting delphinium depends on the climate and the type of delphinium being planted. In general, delphinium seeds should be sown in early spring as soon as the soil can be worked. In areas with mild climates, delphiniums can also be planted in the fall for spring bloom.
Choose a sheltered location: Delphiniums prefer a spot with full sun to partial shade and rich, well-drained soil with a pH of 6.5 to 7.5.Prepare the soil: Loosen the soil to a depth of 12 to 15 inches (30-37 cm) and amend it with organic matter, such as compost or aged manure. Delphinium is a heavy feeder, so the more compost you ad...Dig the hole: Dig a hole that is twice as wide and as deep as the delphinium plant’s root ball.Plant the delphinium: Place the plant in the hole, ensuring that the crown is level with the soil surface. Backfill the hole with soil, gently tamping it down around the plant.Delphiniums may be grown from seed, but this can be quite challenging. Seed should be started indoors early in the year, and those plants will flower the first year. If seeds are sown directly in the ground, those plants will not flower until the following year. 1. Sow the seeds indoorsabout 8 to 10 weeks before the last frost date in your area. Fi...
Botanical name: Delphinium, Consolida. Common name: Larkspur. Annual delphiniums and larkspur (Consolida) are free-flowering easy to grow plants. Add them to borders for long lasting displays all summer or grow as a cut flower to enjoy in the house.
The petals are wider than our Larkspur which, although still not native, do grow wild somewhere in the UK (although your Author has never seen them). The leaves are also lanceolate rather than narrow-linear or pinnately linear.
