Myrtle Spurge
( Euphorbia myrsinites L.)
Myrtle spurge is a member of the Spurge family, and was introduced from Eurasia as a hardy landscape perennial. It is a creeping plant that reproduces by only seed which may remain viable for up to eight years. It is 4-8 inches tall at maturity and may spread up to 18 inches laterally. Myrtle spurge has a shallow root, not extensive, and will not re-sprout growth. Myrtle spurge prefers dry to moist, well drained soils, in areas that receive partial shade to full sun.
The plant produces trailing stems of oblong, blue-green, alternate, fleshy leaves. Yellowish-green heart-shaped bracts enclose the small yellow-green flowers. The bracts have the appearance of flowers. All parts of the plant, including the root, have a milky sap that can be irritating to eyes and skin, so gloves must be worn when handling the plant.
Myrtle spurge is one the weeds that must be managed statewide in compliance with the Colorado Noxious Weed Act. It can easily be controlled by the use of herbicides or hand-pulling and digging. If the plants have been hand-pulled or dug, they can be disposed of by bagging them and sending the bags to the landfill.
