Description

Martins' spurge is a subshrub native to France and discovered in the late 1800s. It is a natural hybrid between the Mediterranean spurge (Euphorbia characias) and wood spurge (E. amygdaloides ssp. amygdaloides). Grow in full sun to partial shade in well-drained soil. It tolerates rocky, dry soil and drought conditions once established. Pinch or prune back to 6" in height in the mid-spring right after the plant flowers to promote a bushy habit.  Always wear gloves when working with this plant to avoid the toxic milky sap.  

Insects, Diseases, and Other Plant Problems:  No serious insect or disease problems. 

Quick ID Hints:

  • Chartreuse bracts subtend apetalous yellow flowers
  • Bushy perennial herb to 3' with variable leaves
  • Milky white latex sap
