The Lenten rose grows as a perennial herb, reaching 28–45 centimetres (11–18 in) high, with glossy green palmate leaves composed of 7–9 leaflets with serrated leaf margins. Leathery in texture, the leaves are evergreen. The cup-shaped pendent flowers appear in late winter and spring, arising in groups of 1–4 on the ends of thick stems rising above the foliage. They have yellow stamens. All parts of the Lenten rose are poisonous.[9] Sap coming into contact with the skin may cause temporary irritation, while ingestion of large quantities can cause burning of mouth and throat, vomiting, abdominal cramping, and diarrhea
