Euphorbia maculata is an annual plant native to North America. It is was the first common from the Waikato north but is now extending its range throughout New Zealand.
It grows close to the ground, often forming a dense mat. It can establish itself in a variety of soils in sunny open areas such as gardens and lawns, and in sidewalk cracks. It reduces the growth of desirable plants. It can develop a central taproot up to 60 cm long.
Euphorbia maculata stems can grow up to 45 cm long along the ground. It has small oval leaves (>10mm) that are arranged in opposite pairs. Their margins are mildly serrated. The leaves are hairier on the underside and on the top side there is a maroon coloured spot in the centre. In dry conditions, they develop a purple tinge.
The flowers are very small, with four pinkish petals and consist only of stamens and pistils grouped in small, flower-like cups, called cyathia, in the leaf axils (where the leaf joins the stem). 1 mm long seeds are formed in a three-celled capsule.
The plant is poisonous and considered carcinogenic. Broken stems secrete a milky sap that is a mild skin irritant and can cause a rash in some people.
Euphorbia maculata can kill sheep grazing in pastures where it is the predominant weed. It is recorded that sheep that have consumed as little as 0.62% of their body weight of this plant have died within a few hours.
