Euphorbia marginata Pursh
Snow-on-the-mountain can be found growing in calcareous soils of the South Texas Plains and Edwards Plateau. It has one to several erect stems that can reach a height of one to three feet. The green leaves near the base are about one to three inches long, while the leaves near the flowers are usually narrower and have white margins. Five white appendages look like the flowers, however, the true flowers are found inside of those appendages. Snow-on-the-mountain blooms from July to October and the seeds are an important food source for quail.
