Jack-in-the-pulpit (Arisaema triphyllum)
Description
“Pet poisonous” – Toxic parts: entire plant esp. roots, leaves Arisaema triphyllum (jack-in-the-pulpit, bog onion, brown dragon, Indian turnip, American wake robin, or wild turnip) is a herbaceous perennial plant growing from a corm. It is a highly variable species typically growing 30–65 centimetres (12–26 in) in height with three-parted leaves and flowers contained in a spadix that is covered by a hood. It is native to eastern North America, occurring in moist woodlands and thickets from Nova Scotia west to Minnesota, and south to southern Florida and Texas. The leaves are trifoliate, with groups of three leaves growing together at the top of one long stem produced from a corm; each leaflet is 8–15 centimetres (3.1–5.9 in) long and 3–7 centimetres (1.2–2.8 in) broad. Plants are sometimes confused with Poison-ivy especially before the flowers appear or non-flowering plants. The inflorescences are shaped irregularly and grow to a length of up to 8 cm. They are greenish-yellow or sometimes fully green with purple or brownish stripes. The spathe, known in this plant as "the pulpit" wraps around and covers over and contain a spadix ("Jack"), covered with tiny flowers of both sexes.
