Cardamine pratensis is our naturalized Bitter Cress, the Lady-Smock of Shakespeare. It came by way of the Atlantic seaports, in ballast or seed-grain, and seems to have made its way westward to the Pacific coast. In general appearance it is the same as our native Cresses but has perhaps a larger and more showy flower. The light, graceful growth and the pinnately divided foliage give the plant a distinct charm. In ancient times it was considered a valuable remedy in heart-disease, so Linnaeus gave it the name Cardamine, signifying heart-strengthening. Its showy flower and abundant nectar invite many insect visitors.
