Dame's Rocket is recognized by its upright habit, fragrant flower clusters and distinctive four-petaled blooms.
Fragrant Flowers
Purple, lavender or white flowers have a noticeable fragrance, particularly during the evening.
Four-Petaled Blooms

Showy upright flower clusters and fragrance make the stems useful for informal cut-flower arrangements.
Where It Fits
Appropriate Uses for Dame's Rocket
Because Dame's Rocket can reseed aggressively, it is best treated as an ornamental species for managed plantings rather than as a native restoration wildflower.
Establishment & Management
Growing Dame's Rocket
Dame's Rocket establishes readily from seed, but its ability to produce abundant seed makes management important.
First-Year Growth
Plants commonly develop primarily vegetative growth during their first season before flowering stems appear during the following growing season.
Site Conditions
Dame's Rocket can grow in full sun or partial shade and performs in a range of soils where adequate moisture and drainage are available.
Flowering
Plants produce terminal clusters of four-petaled flowers, typically in purple, lavender or white, during the spring flowering period.

Important Planting Note
Check Local Regulations Before Planting
Dame's Rocket is not native to California and has become invasive or restricted in some parts of the United States. It can spread readily by seed and should not be used as a substitute for native wildflower species in restoration or sensitive natural areas. Always confirm local regulations and site suitability before planting.
