How to grow a cress caterpillar

What is a cress caterpillar and how do you grow one? This cress caterpillar plant growing activity from the Natural History Museum in London brings crafting fun and food education together, especially for younger kids.

Fast-growing garden cress or cress, “any of several plants of the mustard family (Brassicaceae),” contains potassium and vitamins A and C. It can be added to salads, sandwiches, and soups, or eaten like sprouts.
