Purslane is often described as nutrient-dense because it contains omega-3 fatty acids, vitamin A, vitamin C, some B vitamins, minerals, and antioxidants. The science is most convincing for its nutritional value, while many of the health claims come from early clinical work, review papers, and lab studies rather than large long-term human trials. Some studies suggest benefits for metabolic health, including blood sugar and lipid markers, and there is also interest in its eye-health and antioxidant effects because of its carotenoid content.
Purslane is also interesting because it is one of the few leafy vegetables with meaningful alpha-linolenic acid, a plant omega-3. That makes it especially useful if you want more plant-based omega-3s in the diet.
Purslane is a warm-season plant that grows fast in full sun and free-draining soil, and it does not like cold or waterlogged conditions. Sow it from late spring into summer, keep it lightly watered during dry spells, and thin seedlings so they have room to spread. It can be harvested repeatedly by cutting stems and leaving a little growth behind so it regrows.
For efficient production, succession sowing works well: sow a little every few weeks for a steady supply of leaves. It also does well in poorer soil than many crops, so overfeeding it is usually unnecessary. If you want a crop rather than a weed, keep it in a contained bed or pot, because it can self-seed readily.
Young stems and leaves can be eaten raw in salads, but purslane also works well cooked very briefly, since it softens fast and can become mucilaginous if overcooked. Its slightly lemony, peppery flavor makes it a good match for citrus, yogurt, tomatoes, garlic, eggs, and fish. It also works as a garnish or mixed into soups at the very end.

A very easy one is a quick sauté: cook garlic in olive oil for a moment, add washed purslane, and toss for just 2 to 5 minutes with salt and lemon juice. Serve it as a side dish or fold it into eggs or pasta.
Only harvest from clean ground, since like any wild edible it can pick up contamination from roadsides, spraying, or pet areas. Purslane contains oxalates, so people prone to kidney stones or advised to limit oxalate intake should be cautious. For most people, though, it is a safe and very useful wild food when eaten in normal amounts.
