It grows on almost all parts of the dune but is usually found on the seaward slopes, sending long runners down towards the toe of the dune. The sprawling runners spread out from the woody rootstock, but the large two-lobed leaves are sparse and a dense cover on the sand is rarely achieved except in protected situations.
This plant grows in association with sand spinifex grass and is a useful sand binder, thriving under conditions of the sand blast and salt spray. Ipomoea pes-caprae is a prostrate perennial, often covering large areas; stems long-trailing often several metres in length, rooting at the nodes, glabrous. It has pink petals with a darker centre.
