Sesuvium edmonstonei

A Galápagos-endemic sea purslane that forms fleshy mats on coastal lava, sand and salt-flat margins. Grow it in full sun with warm, even temperatures and a free-draining, mineral, slightly saline-tolerant mix.

Where it grows wild

Coastal zone just above the tide line: lava rock, beach sand and lagoon edges exposed to salt spray, as is typical for Sesuvium.

Recorded at 3–570 m, median 8 m; nearly all records are at the coast.
