[4] Blooming from April to July (about a month earlier in British Columbia),[4] the flower sits at the end of a 15 cm (6 in) leafstalk, often on the ground, hidden by the leaves.

[5] The flowers are hirsute (hairy), cup-shaped, and brown-purple to green-yellow, terminating in three, long, gracefully curved lobes.

Asarum caudatum is found in British Columbia, Washington, Oregon, Northern California,[7] Idaho, and Montana[3] in moist, shaded environments.

[8] It is a typical herb found in the understory of mixed conifer forests under 670 metres (2,200 ft) in elevation, and is often a dominant plant.

Due to the costs of producing seeds with an appendage to attract ants, it is more energetically favorable for the plant to reproduce rhizomatously.
