Invasive Species
Dame's rocket lines roadsides and woodland edges every May looking nearly identical to native phlox — learning to tell them apart keeps you from accidentally celebrating an invasive while the real native wildflower gets overlooked.
Dame's rocket is a pretty, purple-flowered plant originally from Europe that has spread widely across North America and blooms heavily each spring. This week, nearly a thousand people photographed and submitted it to iNaturalist, making it one of the most-spotted plants of the moment. It's a good reminder that some of the showiest flowers in our parks and roadsides are actually non-native species that can crowd out local wildflowers.
Key Findings
967 research-grade observations of dame's rocket were recorded on iNaturalist in a single week, placing it among the top observed plant species.
The observation spike aligns with the plant's peak spring bloom window, when its fragrant purple, pink, and white flowers are most visible and distinctive.
Dame's rocket (Hesperis matronalis) is a non-native invasive biennial across much of North America, frequently misidentified as native wild phlox due to similar flower color and habitat.
