About
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.
Permaculture Functions
- Edible: Young tips where salinity selects for it and harvest rules allow.
- Erosion Control: Succulent mats bind dunes and pond edges.
- Ground Cover: Carpeting cover for salty swales and living shorelines.
- Wildlife Attractor: Shoreline insects use the low dense growth.
Practitioner Notes
- Harvest texture changes faster than color—nip one sample before you commit the whole row to a pick date.
- Shear ragged mats after heat waves; two weeks of ugly beats six months of thatch rot.
- Notebook one weird year—weather anomalies repeat; memory lies, scribbles do not.
- Morning picks hold turgor; afternoon heat steals shelf life even if the cooler feels honest.
Companion Planting
- Mangrove associates
- Salt-tolerant grasses
- Beach sunflower
- Deep forest shade
- Pure freshwater bog without salt—competes poorly with aggressive aquatics
