Euphorbia purpurea
Euphorbia purpurea is a species of Euphorbia known by the common names Darlington's glade spurge, glade spurge, and purple spurge. It is native to the Eastern United States, where it occurs from Ohio and Pennsylvania south to North Carolina. It has been extirpated from Alabama; it was believed lost from Delaware until a population was rediscovered in 1997. This perennial herb grows from a rhizome and reaches a maximum height around one meter. It has slightly hairy, oppositely arranged leaves up to 3 centimeters long. The bracts are purplish in color, giving the plant its name. The bumpy fruit is about 6 to 8 millimeters long. Flowering occurs in May and June. The plant is easily propagated via cuttings, rooting readily. This plant grows in dry to moist to swampy wooded areas and mountain glades. It often grows in saturated soils around seeps near streams. It is not necessarily a wetland species, and it can be found in dry places. It grows in shade and in full sun. In wetter areas it may be associated with Polemonium vanbruntiae, Carex mitchelliana, C. leptalea, Chrysosplenium americanum, Glyceria striata, Cirsium muticum, Rhamnus alnifolia, Scirpus rubrotinctus, Triadenum walteri, and Penthorum sedoides.
