Euphorbia helioscopia (Sun Spurge) is a species of spurge native to most of Europe, northern Africa, and eastward through most of Asia.
It is an annual plant growing in arable land and disturbed ground. It grows to 10–50 cm tall, with a single, erect, hairless stem, branching toward the top. The leaves are oval, broadest near the tip, 1.5-3 cm long, with a finely toothed margin. The flowers are small, yellow-green, with two to five basal bracts similar to the leaves but yellower; flowering lasts from mid spring to late summer.
