Annual Wildflower
Rocket Larkspur
Delphinium ajacis
Syn. Consolida ajacis
A tall annual larkspur with elegant flowering spikes in blue, purple, pink and white
Rocket Larkspur is a fast-growing annual wildflower recognized for tall upright flower spikes rising above finely divided, lacy foliage. Flowers occur in shades of blue, violet, lavender, pink and white, creating a strong vertical element in annual wildflower plantings. Its tall stems and colorful flower spikes also make Rocket Larkspur a popular choice for cut-flower gardens and informal meadow-style displays.
Wildflower Characteristics
Why Plant Rocket Larkspur?
Rocket Larkspur combines tall annual growth, finely textured foliage and colorful vertical flower spikes in a single species.
Tall Flower Spikes
Long upright racemes provide height and strong vertical structure within annual wildflower and ornamental plantings.
Mixed Colors
Flower selections commonly include blue, violet, lavender, pink, rose and white for a varied display.
Fine Foliage
Deeply divided leaves create a delicate, lacy-textured background beneath the flowering spikes.
Cut-Flower Value
Tall flowering stems provide useful vertical material for seasonal bouquets and cut-flower plantings.
Where It Fits
Best Uses for Rocket Larkspur
Rocket Larkspur is particularly useful where a taller annual species is needed to add vertical color and fine texture.
Establishment & Management
Growing Rocket Larkspur
Rocket Larkspur is a cool-season annual that establishes from seed and develops rapidly once conditions are favorable.
Planting Window
In mild-winter areas, fall sowing can allow cool-season establishment. In colder climates, seed can be planted in early spring as conditions permit.
Sunlight
Full sun is preferred, although Rocket Larkspur can tolerate some partial shade.
Soil & Moisture
Plants perform best in reasonably fertile, well-drained soil with adequate moisture during active growth and establishment.
Natural Reseeding
Rocket Larkspur can reseed where mature seed is allowed to develop. Remove plants before seed maturity where volunteers are not desired.
Important Planting Consideration
Rocket Larkspur is an ornamental wildflower and should not be used as a forage species. Larkspur plant material and seed contain toxic alkaloids and should be kept out of areas where livestock or other animals may intentionally graze the plants.
Classic Annual Larkspur
Tall Color with Fine-Textured Foliage
Rocket Larkspur provides a growth form that is different from many common annual wildflowers. Finely divided foliage creates a light base while long flower spikes rise vertically above the stand, adding height, movement and concentrated color to wildflower and cut-flower plantings.
