Here in Houston purslane is often found thriving in the cracks of sidewalks and driveways during the worst of summer's heat. The tiny black seeds are prolific and will easily grow in containers, flowerbeds and just about anywhere else. Purslane will also reproduce from plant fragments, making it very easy to propagate.
Purslane is very rich in omega 3 fatty acids as well as other nutrients. It is delicious raw, steamed, fried or cooked. The thickest stems can also be pickled using the recipe & canning time of pickled okra.
The toxic Spotted Spurge (Euphorbia maculata) shows up at the same time as Purslane and while they may look somewhat similar to novices, they are very easy to tell apart. Spotted Spurge stems always remain thin, never even becoming even as thick as a pencil lead whereas Purslane stems can become thicker than a pencil's shaft. The spurge's stem always is a dark red while purslane stems very from green to purple, though are often "earthworm" pink/red. Spurge bleeds a white, latex sap but purslane's sap is clear if it even is seen. Spurge leaves remain small and flat while purslane leaves become thickly succulent and as large as the first joint of a pinkie finger.
