Verdolaga in Montreal

As a companion plant, Purslane provides ground cover to create a humid microclimate for nearby plants, stabilizing ground moisture. Its deep roots bring up moisture and nutrients that those plants can use, and some, including corn, will "follow" purslane roots down through harder soil than they can penetrate on their own. It is known as a beneficial weed in places that do not already grow it as a crop in its own right. http://en.wikipedia.org/wiki/Portulaca_oleracea#Companion_plant
