As such, many variants have been named (C. It is a very aggressive weed, one of the ten most noxious weeds worldwide (J. Portulaca oleracea is a highly variable species with worldwide distribution in temperate to warm regions and is the most winter-hardy of all the portulacas. Currently, it is fed to poultry to reduce egg cholesterol. It has long been used as fodder and may have been present in the New World in pre-Columbian times (R. (1992) have shown Portulaca oleracea to have the highest content of omega-3 fatty acids and antioxidants of any green leafy vegetable examined to date, suggesting that common purslane should be considered for its nutritional value and not for its weediness.
