Appearance

Its leaves are kidney-shaped and persistent. Underground shoots are shallow-growing, fleshy rhizomes that branch to form a clump. The flowers bloom from April through June, are hairy, and have three sepals, tan to purple on the outside and lighter inside, with tapered tips and bases fused into a cup.

Pollinated flowers develop into a pod, which splits open when ripe to reveal seeds with elaiosomes, structures that are eaten by ants .

The diploid chromosome number is 26.

The flowers attract small, pollinating flies that emerge from the ground during early spring looking for a thawing carcass to munch on. It's position on the ground allows it to be readily found by the emerging flies. The color of the flowers are similar to that of decomposing flesh. So, the flies enter the flowers and feast upon the pollen. Some of the pollen attaches to their bodies and is taken with them when they visit the next wild ginger flower.

Uses

The long rhizomes of ''A. canadense'' were used by Native Americans as a seasoning. It has similar aromatic properties to true ginger , but should not be used as a substitute because it contains an unknown concentration of the carcinogen aristolochic acid and asarone. The distillate from the ground root is known as Canadian snakeroot oil. The odor and flavor are spicy. It has been used in many flavor preparations.

Native Americans used the plant as a medicinal herb to treat a number of ailments including dysentery, digestive problems, swollen breasts, coughs and colds, typhus, scarlet fever, nerves, sore throats, cramps, heaves, earaches, headaches, convulsions, asthma, tuberculosis, urinary disorders, and venereal disease. In addition, they also used it as a stimulant or appetite enhancer, and as a charm. It was also used as an admixture to strengthen other herbal preparations.
