What is the plant

Jack-in-the-pulpit (Arisaema triphyllum) is a unique plant with an interesting growth habit. The structure that most people call the jack-in-the-pulpit flower is actually a tall stalk, or spadix, inside a hooded cup, or spathe. The true flowers are the tiny, green or yellow-tinged dots that line the spadix. The entire structure is surrounded by large, three-lobed leaves that often hide the spathe from view. In late summer or fall, the spathe falls off and the flowers give way to decorative wands of bright red berries.

Additional
Jack-in-the-pulpits are poisonous plants, the corms (if eaten raw) being considered especially toxic. Native Americans cooked the corms after soaking and drying them, as preparation for both medicinal and culinary uses (thus the common name, "Indian turnip"). But only experts should try this.
