Sea purslane is the succulent carpet of coastal flats—fleshy leaves, reddish stems, and the casual ability to drink brackish water while your lettuce throws a fit. Young tips are eaten in some cuisines; ID carefully and respect local harvest rules near protected shores. Native-ish coastal vibe along both coasts; great for salty swales, living shoreline buffers, and “nothing else will grow here” beds. ☀️💧 Sun and Water Requirements: Full sun. Tolerates salt spray and periodic inundation; also handles garden irrigation if drainage exists—do not marinate it in stagnant muck. ✂️ Propagation: Cuttings root obnoxiously easily; seed where legal and ecologically appropriate. 🌾 Harvest / Best Use Timing: Snip young tips when sourcing is legal and clean—respect protected shoreline rules.
