Besides C. impatiens’ neat mechanical adaptation for self-sowing, its seeds can spread by moving water or by latching on to clothes, animals, even the tires of bikes or cars. Hand-pulling young plants before they set seed is the preferred way to eradicate bittercress, making sure to get the roots. Pulled plant material can then be composted.
The leaves and young shoots are edible raw or cooked. When moving any mature bittercress plant material be careful not to spread the seeds to other locations.
For native alternatives to narrowleaf bittercress try planting wild stonecrop, heartleaf foamflower, wild geranium, woodland phlox, eastern red columbine, wild ginger, or wild strawberry.
