Plant or Weed ID: Purslane

Need an ID please. I've been throwing seeds out here and there and not keeping track of them. Does anyone know if this is a weed or something I'd want to keep? Looks like leaf miners are about. Ugh. In this area I planted babies breath, dianthus and I forget the what the third thing was.






Edited to add ID. Purslane an edible weed! Thank you all! :) :)
