leafy spurge

A native, deciduous, herbaceous perennial which produces new stems from buds on an underground rhizome in spring, up to approximately 90cm (3ft) high. The rhizome can become extensive when mature with deep vertical roots capable of penetrating several metres into the soil. Clusters of small yellow-green, floral bracts are produced spring and summer, followed by copious seed production. The plant has little or no ornamental value and has become a nuisance, non-native weed in several countries because of its ability to regenerate from its deep root system and copious seed production
