- Description
-
Prostrate Spurge is an annual herb in the Euphorbiaceae (spurge) family with prostrate to ascending stems with round or oblong leaves. It is native to the tropical/sub-tropical areas of the Americas, Mexico and in the south-central U.S. Euphorbia is named after Euphorbus, a Greek physician who served King Juba of Numidia in 12BC. Prostrata is for the way it lies on the ground. It is weedy and can be found in disturbed areas along the side of the road, waste areas, railroads even sidewalk cracks. It can be found in lawns and gardens. Extracts from the plant are used in India as a treatment for hemorrhoids.
The plant prefers full sun to partial shade in dry, sandy or gravelly soils. Seedlings are very small but will flower when young. This plant is a prolific seeder. Seeds have limited or no dormancy and germinate quickly.
This plant is best found in native gardens or meadows and lawns.
Insects, Diseases and Other Plant Problems: Prostrate spurge has no serious insect or disease problems. Some people experience skin rashes from contact with the toxic sticky plant sap of euphorbias.
Quick ID Hints:
- Leaves and stems have white curled or crinkled hairs.
- Stems are red colored.
Management for Spurges: Because spurges flower when young and have little or no seed dormancy, weed populations can increase rapidly. Remove plants when young to reduce seed production. They are time-consuming to hand weed due to the number of seedlings that form. Some species may forcefully discharge seeds. Spurges are well-managed by most pre-emergence herbicides labeled for use.
