Myrtle Spurge: A Promised Plant Turned Invasive Weed in the Wasatch Front Area

In the foothills and wild lands of the Wasatch Front area, a once-promised ornamental plant has become an invasive and harmful weed. The Salt Lake County Health Department is warning residents to stay away from myrtle spurge, which was originally brought to Utah as a deer-resistant and drought-tolerant plant. However, this plant has now spread to natural areas and is considered harmful to plants and wildlife.

Myrtle spurge is easily recognizable by its blue-green triangular leaves and milky latex sap. In the spring and summer months, it produces small flowers with yellow bracts. This plant spreads through seeds and can project them up to 15 feet, making it a formidable force in natural habitats.

Despite its potential benefits, myrtle spurge can cause skin irritation when contact with its white sap is made. Symptoms include rashes, redness, swelling, and blisters. If exposure does occur, it’s important to flush the affected area with water immediately to prevent further irritation. The state of Utah classifies myrtle spurge as a noxious weed and restricts its sale.
