A native of Europe, and now distributed from Atlantic Coast to Pacific Coast.
An annual, upright weed that is very common in irrigated landscape. Like other spurge species it exudes a white, milky sap when stems or leaves are broken, and plant parts are reported to be toxic to both humans and livestock when eaten.
Mature plants can grow to 18 inches tall, with a solitary central stem or multiple stems branching from the base of the plant. Stems branch again near the tops of the main stems. Stems are smooth, and green to reddish-green.
Leaves occur on short stalks, singly along the stems. The lower leaves are round and the leaves just below the flowers are somewhat heart-shaped and without stalks. Foliage tends to be light green to yellow-green.
Flowers are very small and greenish, forming in small clusters at the tops of the stems.
Characteristicts Important to Control:
An annual weed that favors undisturbed landscape habitats with sufficient moisture. Easily removed by hand due to the upright growth and weak, fibrous roots.
