Overview
Ipomoea imperati is a trailing perennial vine of coastal dunes, sending out prostrate stems 3–10 feet (1–3 m) long that root at the nodes and spread across open sand. The fleshy leaves vary from oblong to deeply three- to five-lobed or fiddle-shaped, 1–2.5 inches (2.5–6 cm) long, thick-textured to resist salt and drying. Funnel-shaped flowers 1.5–2.5 inches (4–6 cm) across open in the morning, white with a pale yellow throat, and close by midday. Flowering continues through the warm season. The vine grows on upper beaches and foredunes along tropical and subtropical coasts of the Americas and other warm regions, where its rooting stems help bind shifting sand. I. imperati tolerates salt spray, sandy soil, and drought but needs full sun and sharp drainage, is damaged by frost, and does not persist away from sandy coastal conditions.
Native Range
Ipomoea imperati grows on tropical and subtropical coasts worldwide, including the Atlantic, Gulf, and Pacific shores of the Americas. It occupies upper beaches, foredunes, and sandy coastal flats within reach of salt spray.Suggested Uses
Used in dune stabilization, coastal gardens, and sandy seaside banks. Set in full sun on open sand and spaced 3–5 feet (0.9–1.5 m) apart, it spreads to cover and hold shifting ground.How to Identify
