Description

Close-up on Arisarum vulgare

Arisarum vulgare reaches on average 10–30 centimetres (3.9–11.8 in) of height. The leaves of this geophyte plant are basal only, wide, ovate to arrow-shaped, with a petiole 12–15 centimetres (4.7–5.9 in) long. The stems are erect and unbranched, usually mottled and grow directly from the underground rhizome. A single leaflike bract (spathe) forms a purplish-brown or olive green striped tube about 5 inches long, with an open upper part helmet or hood-shaped curved forward. It encloses a fleshy greenish clublike spike (spadix) bent forward, protruding from the tube and bearing at the bottom minute purple violet flowers. The 20 male flowers are located above the four to six female, with sterile flowers completely missing. The flowering period extends from October through May. The sexes are united in the same individual plant. Pollination is granted by insects (entomophily). The fruits are greenish berries of about 1 centimetre (0.39 in)long.
