Purslane, Portulacca oleracea

Although considered primarily a weed here in the U.S. this humble, low-growing plant is valued as a nutrient-rich salad green (eaten raw or cooked) and for its medicinal qualities in many other countries. Its use in both regards dates back to ancient time and particularly in Greeece archaeobotanical evidence of this plant has been found. Purslane has a delicious if slightly sour flavor and is quite unusual for its high content (more than any other leafy green) of omega-3 fatty acids, which are most commonly found in seeds and in fish.
