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.

Annual Wildflower Mixes Adds tall flower spikes and cooler blue, purple and pink tones to mixed annual plantings.
Cut-Flower Plantings Long flowering stems make Rocket Larkspur especially useful for seasonal bouquets.
Meadow-Style Plantings Tall, slender flowering stems rise naturally above lower-growing annual wildflowers.
Borders & Mass Plantings Upright flower spikes provide a strong background or middle layer in larger displays.

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.
