Adlumia fungosa B. S. Walters

Forests, rocky shores, and thickets; seems to do well on rocky islands and shores of the northern Great Lakes; in the southern half of the Lower Peninsula occasional on forested dunes and appearing sporadically from the seedbank after forest disturbance such as logging and clearing.

Our only vine in this family, distinctive in the persistent spongy corolla of definitely united petals.This is a genus of only two species, the other in eastern Asia.

Though native in forest settings, this is occasionally cultivated as an ornamental, and at least the Ingham Co. specimen suggests "Probably escaped from cultivation."  Often associated with some soil disturbance, this species can occur in small numbers in rocky woods and on cliffs and rocky shores, especially in limestone areas near the straits. Here and elsewhere, may occasionally become briefly abundant after clearlng, then quickly retreating into the seedbank.
