This plant is trailing along a rocky beach just out of reach of the high tide, climbing amongst driftwood, a feral Malus tree, and Rubus armeniacus. It gets nearly full sun except some intermittent shade from the Malus. The leaves have a cordate base and a general heart shape with an acuminate blade tip; they range in size from 3 to 8 inches long; leaf margins are entire but relatively sinuose. Entire plant glabrous. Flowers white, bisexual, actinomorphic, gamopetalous, and 5-merous; the majority have an approximately 3 inch diameter.

It stands out from the native C. sepium because of its overlapping bracteoles. But it may be a hybrid or other species.
