Care
Exposure
Sea purslane prefers full sun for optimal growth, but tolerates light part shade. Plant it in a coastal area or in a well-open rock garden. Its low-growing habit makes it ideal for the front rows or edging.
Soil
This plant thrives in sandy, gravelly, and very well-drained soil, mimicking its natural coastal environment. It tolerates poor and even salty soils. Improve drainage with coarse sand or gravel if your soil is too compact.
Watering
Once established, this succulent needs little water: moderate watering during the growing season is sufficient. Avoid standing moisture, which could rot the roots and fleshy leaves. In winter, watering is minimal.
Pruning and maintenance
No specific pruning is needed: this low and compact plant maintains itself naturally. Simply remove dead or damaged stems in spring to keep a harmonious shape.
Fertilizing
Sea purslane thrives in poor soils and doesn't require regular feeding. A light application in spring is enough if you want to boost flowering. Choose a balanced fertilizer for coastal plants or succulents.
Diseases and pests
This hardy plant is resistant to disease. Watch out for rot if humidity is excessive or drainage fails. Few pests target it, but occasionally inspect leaves if the plant is weakened.
Did you know?
Sea purslane colonizes the beaches and dunes of the Atlantic coast from the Arctic to temperate regions. Its ability to survive salt spray and extreme conditions makes it a pioneer species essential for beach stabilization. Its fleshy leaves accumulate fresh water, allowing it to thrive where few other plants can establish themselves.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
