Scientific name: lepidium sativum
Cress is a herb with a very sharp, peppery taste that is very easy to grow. It is related to mustard. Cress can be grown inside by sprinkling the seeds over some damp potting soil and left on a window ledge. Cress can be harvested simply by cutting the plants off with scissors when they have a few leaves. Cress is very tasty on salads, or in egg and cress sandwiches.
