SN – State noxious weed PS – State prohibited weed seed Leafy spurge is a serious pest across the northern great plains, displacing grasses and other plants normally consumed by cattle. It infests over 3 million acres of land in 29 states. The roots of leafy spurge can exceed 20 feet in depth. When broken, stems and leaves exude a milky latex sap, which can cause minor skin irritation or blindness on contact. Ripe seed capsules rupture when touched, throwing seeds up to 15 feet. |

Unitl recently, the leafy spurge in North America was thought to be Euphorbia esula. A 2016 review by Berry, et al., at Flora of North America, showed that the naturalized species in North America is actually Euphorbia virgata. There are herbarium specimens of Euphorbia esula in North America, indicating that it was here at one time. However, it has not persisted, and is now considered absent. Euphorbia esula is not considered a weedy species and is restricted to certain parts of Europe. Euphorbia virgata is a weedy species found throughout Europe, Asia, and now North America. |
