Horticulture/Euphorbia maculata

Euphorbia maculata, variously called Spotted spurge or Prostrate spurge, is an annual plant in the family ../Euphorbiaceae/, native to North America. It grows in sunny locations and a variety of soils, and frequently found as a weed of gardens and lawns, and can also grow well in the cracks of hardscapes or walls.

Description
Euphorbia maculata is a low-growing, spreading, annual plant with reddish stems. The leaves are bluish-green on the margins, and red along the midribs. The flowers are tiny, and are produced within a few weeks of germination, quickly followed by the small seeds.

Control
Early action is crucial with this weed because of the short period between germination and the setting of seeds. The seeds will germinate in wood and stone mulches as well.
