If you are like most gardeners and homeowners you don’t want uninvited obnoxious guests. Myrtle Spurge is a noxious weed which can take over your yard and open spaces. It also has a latex sap which is toxic to children, adults and pets. It was introduced as an ornamental plant and now is an interesting plant gone bad! Thanks to the efforts of Colorado residents and volunteers, it’s getting closer to being eliminated. You can help by learning how to identify it, get rid of it, or report it to have others catch it. If you like something similar in your garden you might try a native plant Kannah Creek Sulphur flower (Eriogonum umbellatum) or a sedum which attracts bees and pollinators.
Myrtle spurge (Euphorbia myrsinites) is a List A noxious weed, and the Colorado Noxious Weed Act requires its eradication. Other states may not have issues with it but have their own lists of noxious weeds. Nurseries are not to sell it in Colorado. Some cities like Lafayette fine homeowners who have it on their property.
Hand pulling and digging up Myrtle spurge are most effective. Always wear gloves, long sleeves, and eye protection when pulling and bagging myrtle spurge and don’t add it to compost. The toxic, milky sap causes severe skin irritations, including blistering. Stories are told of children going to the emergency room after contact with the sap then rubbing their eyes or face. This plant is poisonous if ingested, causing nausea, vomiting, and diarrhea. All plant parts are considered poisonous.
Multiple “Purge Your Spurge” events will take place on Saturdays this spring for residents to bring in bags of Myrtle spurge and receive free native plants or seed in exchange.
