About this species

Tree-huggers beware – even the trunk of this tree has vicious stinging hairs, which cause both pain and intense itching. Think of European stinging nettle (Urtica dioica), which is from the same plant family (Urticaceae), and multiply! But from several steps away it is a pretty tree, looking a bit like a papaya tree (Carica papaya). It grows on rocky hillsides in East Africa and Madagascar and, amazingly, people have found a way of using the bark fibres for basketry and rope-making.
