Trending: dame's rocket (Hesperis matronalis) — 932 observations this week
iNaturalist Community
Invasive Species
Those showy purple clusters lining roadsides and garden edges in June are dame's rocket, not native phlox — and knowing the difference helps you decide whether to pull it before it reseeds aggressively or let it feed the early pollinators passing through.
Dame's rocket is a tall, fragrant plant with clusters of four-petaled purple, pink, or white flowers that blooms in late spring and early summer. It originally came from Europe but has spread widely across North America, often popping up along roadsides, woodland edges, and gardens. Right now it's blooming in full force, and nearly a thousand people spotted and recorded it this week alone.
Key Findings
932 research-grade observations were submitted in a single week, placing dame's rocket among the top trending plant species on iNaturalist.
The observation spike aligns with its peak bloom window in late spring to early summer across temperate North America.
Dame's rocket is frequently misidentified as native garden phlox, but can be distinguished by its four petals (phlox has five).
