Botanical Name : Arisaema triphyllum
Species: A. triphyllum
Common Names: Jack-in-the-Pulpit, Bog onion, Brown dragon, Indian turnip, Wake robin or Wild turnip
Arisaema triphyllum is a highly variable species typically growing from 30 to 65 cm in height with three parted leaves and flowers contained in a spadix that is covered by a hood.
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 cm long and 3-7 cm 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 long. They are greenish-yellow 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. The flowers are unisexual, in small plants most if not all the flowers are male, as plants age and grow larger the spadix produces more female flowers. This species flowers from April to June. It is pollinated by flies, which it attracts using heat and smell. The fruit are smooth, shiny green, 1 cm wide berries clustered on the thickened spadix. The fruits ripen in late summer and fall, turning a bright red color before the plants go dormant. Each berry produces 1 to 5 seeds typically, the seeds are white to light tan in color, rounded, often with flattened edges and a short sharp point at the top and a rounded bottom surface. If the seeds are freed from the berry they will germinate the next spring, producing a plant with a single rounded leaf. Seedlings need three or more years of growth before they become large enough to flower. In addition the plant is not self pollinating since the male flowers on a specific plant have already matured and died before the female flowers of that same plant are mature. So the female flowers need to be pollinated by the male flowers of a different plant. This inhibits inbreeding and contributes to the health of the species.

It is hardy to USDA plant hardiness zone 3.
If the plant is properly dried or cooked it can be eaten as a root vegetable.
The plant contains calcium oxalate crystals as raphides in all parts, and because of this consumption of the raw plant material results in a powerful burning sensation. It can cause irritation of the mouth and digestive system, and on rare occasions the swelling of the mouth and throat may be severe enough to affect breathing.
A preparation of the root was reported to have been used by Native Americans as a treatment for sore eyes. Preparations were also made to treat rheumatism, bronchitis, and snakebites, as well as to induce sterility.
The oxalic acid in jack in the pulpit is poisonous if ingested. Care should also be taken to avoid confusion with poison ivy, which has 3 leaflets somewhat similar in appearance.
