A patch of Dame's Rocket growing by a raliway.

This is an invasive non-native plant. It's not quite as bad as Garlic Mustard (Alliaria petiolata), but still bears watching. If you allow this plant to grow in your garden, keep a close watch on it.
I have seen areas completely taken over by Dame's Rocket.
