Hesperis matronalis 6-3-10 1

Dame’s Rocket is a biennial in the Mustard family (Brassicaceae).  It’s native to Eurasia, and is planted in the U.S. as a garden flower.  It’s flowers range from bright pink to white.

Unfortunately, it naturalizes easily, and becomes invasive in natural areas.

The flowers of Dame’s rocket resemble Phlox, except that they have 4 petals, and Phlox has 5.

We have one small area where Dame’s Rocket grows – along the road, at the edge of the wetland.

I’ve been pulling all the flowering plants I can find, and each year there are fewer of them.
