Take me back to the marshes, where the sands move beneath me, where the salt lies gently on the breeze.
Our salt marshes are precious, soft, shifting, places wefted between land and sea. The plants here are rare, vital, and have their own succulent-salty ways of being.
Sea purslane (Sesuvium portulacastrum) is a halophytic* plant with a salty, olive-like flavour and some fascinating properties. I spent much of my childhood living next to a salt marsh, and find great comfort and nostalgia in nibbling these rough fleshy leaves.
*A halophytic plant is one that is adapted to grow in environments with high salinity, like salt marshes. These plants have specialised physiological mechanisms to manage and tolerate the high salt concentrations in their environment. This can include fascinating features like salt excretion glands, succulent leaves to store water, and the ability to compartmentalise and sequester salt within their tissues. That’s why these plants taste salty and mineral-rich.
This beautiful silvery being has both anti-inflammatory and wound-healing properties, and can be applied topically to treat skin conditions, cuts, and sores. It is also used as a remedy for gastrointestinal issues.
Sea purslane is edible and tasty, and can be eaten raw or cooked. Wild sea plants are incredibly high in minerals, so are wonderful nutritionally as well as being delicious.
This plant is incredibly tolerant of saline environments and is sometimes used in phytoremediation to improve soil quality in salt-affected areas. Its ability to thrive in high-salinity soils can help reclaim polluted, over-farmed, and degraded lands, improving the soil for other beings to thrive.
**Recent studies have explored the use of sea purslane in bioremediation, particularly in coastal areas polluted by heavy metals. The plant has shown potential in absorbing and accumulating heavy metals from contaminated water and soil, thus helping to clean up polluted environments. This means it is really important to forage in the cleanest areas you can.
