Giant Hogweed is an invasive, non-native plant introduced from Asia. It has large, flat-topped to slightly dome-shaped flower (similar to Queen Anne’s Lace/Wild Carrot) and seed head and a bumpy or bristly stem. It can grow up to five metres in height. Skin contact with Giant Hogweed sap may cause severe skin rashes when exposed to sunlight.
Habitat: Roadsides, stream banks, waste areas, yards

Stinging Nettle is from half a metre tall to three metres in height. Stems and leaves are covered with short, stinging hairs which can cause irritation and inflammation if touched with bare skin. Flowers are in clusters with separate flowers attached by short stalks along a central stem about 1-7 centimetres (cm) long.

- Wear closed-toed shoes
- Wear long-sleeved shirts
- Wear long pants, tucked into your socks

- After outdoor activity put your clothes in the dryer
Check yourself and your children:
