Sesuvium portulacastrum is a sprawling perennial herb that grows in coastal areas throughout much of the world. It is commonly known as shoreline purslane or (ambiguously) "sea purslane," in English, and dampalit in Tagalog.
It grows as a sprawling perennial herb up to 30 centimetres (12 in) high, with thick, smooth stems up to 1 metre (3.3 ft) long. It has smooth, fleshy, glossy green leaves that are linear or lanceolate, from 10–70 millimetres (0.39–2.76 in) long and 2–15 millimetres (0.079–0.591 in) wide. Flowers are pink or purple.
It was first published as Portulaca portulacastrum by Carl Linnaeus in 1753. Six years later Linnaeus transferred it into Sesuvium, and it has remained at that name ever since, with the exception of an unsuccessful 1891 attempt by Otto Kuntze to transfer the species into a new genus as Halimus portulacastrum.
Distribution and habitat
It grows in sandy clay, coastal limestone and sandstone, tidal flats and salt marshes, throughout much of the world. It is native to Africa, Asia, Australia, North America and South America, and has naturalised in many places where it is not indigenous.
