Although maligned in modern times due to its hairy leaves that cause skin irrititations, Stinging Nettle actually has many favourable attributes. It is a nutrient-rich food (cooking neutralizes the stinging) and both the leaves and roots boasts a number of potent medicinal properties. Nettle can also be grown as a dye plant as well as for its fiber in the stems to make fabric or paper. These perennials provide a habitat for butterflies and other beneficial insects as well. For consumption, the leaves should be harvested when young and tender in late winter/early spring. Pick the top-most two or three pairs of leaves. Once mature, whole plants can be dug up. Nettles can become quickly invasive and requires careful management–consider growing in containers.
