Weed of the Month: Painted spurge (Euphorbia cyathophora)
By Rae Wear (Rae is from the Native Nursery on Coochiemudlo Island)
This month’s weed is easy to identify because it resembles another member of the Euphorbia family, the Poinsettia (Euphorbia pulcherrima). Painted spurge grows up to a metre high, and the stems and leaves exude a toxic milky sap. The flowers are small, yellow-green and inconspicuous; the red petals are really leaves. It is native to tropical America and was probably introduced to Australia as a garden plant. Painted spurge likes disturbed sites and can be found in many of the sandy areas of Coochiemudlo’s Emerald Fringe.
Although easy to pull out, it multiplies quickly as seed capsules explode when mature and disperse new plants over a wide area.
