Weed of the Week: Myrtle Spurge

Euphorbia myrsinites, also known as donkey tail, burro tail, or myrtle spurge, is native to southeastern Europe and Asia Minor but was brought to Utah as a drought-tolerant ornamental. Unfortunately, it is a highly invasive weed that spreads quickly and crowds out native vegetation in our foothills and open spaces. The milky sap is toxic and can cause blindness if it comes in contact with the eyes. The plant blooms in spring and produces seed pods that pop open in early summer, throwing the seed a distance of several yards. It is listed as a Class 4 Noxious Weed in Utah, meaning that it is illegal to sell or propagate it. The best way to control it is to dig or pull it out of the ground and dispose of it before it blooms, or at least before the seeds have a chance to mature.
