Euphorbia rigida, also known as gopher spurge or upright myrtle spurge, is a member of the genus Euphorbia. Gopher spurge is a vascular plant. It has appeared spontaneously in California wilderness but is not considered a noxious weed.[1]


Gopher spurge is native to the Mediterranean Basin and the Middle East, where it is considered a weed.[2] Americans and Brits commonly use it in their gardens. It is a Spring blooming plant. The plants wounds leak a milky sap which can cause skin irritation.[3]


Research has been done on using Euphorbia rigida as a bio fuel. It has been shown to produce 137 gallons of oil per acre.[4]
