Species of flowering plant
Arisaema triphyllum, commonly known as Jack-in-the-pulpit, is a species of flowering plant in the Araceae family. It is native to eastern North America and is known for its distinctive flower structure and unique reproductive strategy.
Description[edit]
Arisaema triphyllum is a perennial herbaceous plant that typically grows to a height of 30 to 65 cm. The plant is characterized by its trifoliate leaves, which consist of three leaflets. The central leaflet is usually larger than the lateral ones. The plant's most distinctive feature is its inflorescence, which consists of a spadix ("Jack") enclosed within a spathe ("pulpit").
