(50 days. Portulaca oleracea sativa) Not the matting weed wildling, but the big garden variety that is upright and large-leafed. Does not become invasive, although it will self-sow and perform well if tended. Used by tradition as an esteemed vegetable, and for soup in the southwest. Use it raw for its juicy and lemony flavor as a summer salad item. One of the highest vegetable sources for omega-3 fatty acids and well-documented for beneficial cardiovascular and cholesterol controlling effects. Chickens grazing on Purslane will produce high omega-3 eggs. The species has no freeze tolerance, but excels in the hottest weather.
