Advisory: In the Gentle World garden, I have noticed that purslane does seem to crowd out young shoots, but does not seem to affect established plants. For this reason, I think it is best to harvest purslane growing near young shoots until they mature.
Recipe
Edibility: Purslane contains more Omega-3 fatty acids than any other leafy vegetable. It is also high in antioxidants like vitamins A, C and E, and essential minerals like iron, magnesium, calcium and potassium.
You can enjoy it in a salad, stir-fried, or cooked like spinach (the berries are also eaten like capers.)
It has also been used to treat gastrula intentional gastro-intestinal disorders, as well as to relieve sores and insect or snake bites on the skin.
