The widespread Arisaema triphyllum is one of our favorite US native wildflowers. This hardy Jack-in-the-pulpit emerges in very early spring with a solitary stalk of one to two leaves, each with three leaflets. The height varies genetically from 1 -3' tall, but 18" is normal. On the top of the stalk is its namesake pitcher. As the common name indicates, the hooded pitcher-like spathe has an appendage (spadix) that resembles a preacher in the pulpit...I bet this one was named during one heck of a hangover! If pollination of the flower occurs, you will have a stalk of bright red berries as the plant goes summer dormant. Moist soils are best, but Arisaema triphyllum has amazing short-term drought tolerance. Arisaema triphyllum offsets, so you will soon have a nice colony.
