What is the plant
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. The flowers are unisexual and sequential hermaphrodites, 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 fungus gnats, which it attracts by smell and are trapped by the flower. They manage to escape from the male inflorescences, but cannot do so when they fall inside a female inflorescence. Other insects are known to visit the flowers as well, such as gall gnats and beetles. The fruits 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.
