It seems that whenever I search for flowering plants to photograph I find myself having to “man up” and admit that I’m fond of aliens. The blooms of Wild Domestic Apple, Autumn Olive, Black Locust and, now, Dame’s Rocket, have all been impressive — and not one of these plants is native to this area.
Dame’s Rocket (Hesperis matronalis; Mustard family) is everywhere now, especially on disturbed sites with moist soils – abandoned fields, forest openings and edges, the neglected borders of lawns, etc. Native to Eurasia and introduced over 200 years ago, it is now widely distributed across most of North America. Extensive, nearly pure stands are common and, in late spring, a dominant landscape feature.

Dame’s Rocket is easily mistaken for a garden Phlox. An alternate leaf arrangement and 4 petals distinguish it from this plant group, which has opposite leaves and 5 petals.
The Forest Invasive Plants Resource Center is keeping a watchful eye on the spreading Dame’s Rocket, monitoring the “invasion” to determine threats to native flora and fauna. I monitor Dame’s Rocket for it’s natural beauty and, more importantly, the impressive array of colorful wildlife species that are attracted to the prolific, fragrant bloom.
