Common Nettle

Urtica dioica

Common Nettle grows up to 1.5 metres in height. Nettle flourishes in nitrogen-rich soils and can be found in urban wastelands, parks and undisturbed corners of the city.

Its leaves are arranged in opposite pairs with serrate margins that are covered with stinging hairs. These hairs contain irritating histamine. The name Urtica comes from urere, which in Latin means ‘to burn’.

The young leaves can be eaten after being steamed or cooked.
