Euphorbia rigida also known as Gopher Spurge or Upright Myrtle Spurg is a member of the genus Euphorbia. This genus is one of the largest in the world with 2,000 species[1]. Gopher Spurge is a vascular plant meaning it is a non-woody plant that is not a grass. It has appeared spontaneously in California wilderness but is not considered a noxious weed[2].

Gardening

Gopher Spurge is native to the Mediterranean Basin and the Middle East, where it is considered a weed. [3] Americans and Brits commonly use it in their gardens. It is a Spring blooming plant. After flowers have faded the plant should be cut back to the ground to allow for next years growth. The plants wounds leak a milky sap which can cause skin irritation. It should not be planted near fish ponds as the sap can be harmful to fish [4].

Bio Fuels

Research has been done on using Euphorbia rigida as a bio fuel. It has been shown to produce 137 gallons of oil per acre. [5]
