Purslane (portulaca oleracea) is yet another weed I have growing wildly in my garden, but only now have I decided to stop thinking of it as a pesky weed. I am even considering collecting some seeds in the fall, and growing some in its own little garden – away from my onions and leeks which it likes to snuggle up to.
Canadian Gardening says this about it:
Nutritionally, purslane is a powerhouse. It has more than double the omega-3s that kale has and, as far as I know, more than any other leafy green ever analyzed. It has over four times the vitamin E of turnip leaves, more than any other leafy green ever analyzed. It has glutathione and other antioxidants and about as much iron as spinach. It also has reasonable amounts of other nutrients as well as phytochemicals, like all these leafy greens. So purslane is no slouch, not a poison, and definitely worth eating.
Rich in omega-3s
Many people studying the Mediterranean diet think that it is foods like purslane and other omega-3 greens that give the Greeks their good balance of fats. Olive oil only contributes some of the omega-3s; the greens, walnuts, oily fish, and a few other foods give them the rest of what they need.
If you pick only the succulent stem tips, the plant will continue to grow. Remove flowers as they appear, unless you wish to collect seeds. The flavour is lemony-sweet, and they are crunchy when fresh.
I used cabbage, shredded carrot, purslane, olive oil, salt and cider vinegar to keep it as simple as possible. Other herbs, shredded beets, jerusalem artichokes, or even a base of lettuce or some other greens would work just as well.
