A common day-flowering perennial, similar to the Evening Primrose, growing from one to three feet high, and usually branched. The sparingly toothed oblong or lance-shaped leaves are either clasping or short-stemmed. The hairy stalk and the closely set alternating leaves are frequently stained with purple. The large yellow flowers are grouped in leafy terminal spikes. The four long, heart-shaped petals are thin-textured and delicately veined. The long yellow stamens spread from the centre, and the buds start from the axils of the topmost leaves. The seed case is strongly ribbed and winged. This plant is found from June to August in dry, sandy soils from Nova Scotia to Georgia, west to Minnesota and Louisiana. During the winter and early spring, the beautiful leaf clusters of the Primrose are remarkable for their wonderful symmetric arrangement, and as William Hamilton Gibson has said, "are a perfect pattern for the modeller, the sculptor, decorator, or wood-carver."
