    $\begingroup$ I am not familair with the flora of the New World, but this looks like Common purslane, Portulaca oleracea $\endgroup$ – RHA Jul 16 '18 at 18:36

    $\begingroup$ @RHA is correct, it is Portulaca oleracea (RHA you should put this as an answer). This is purslane in one of its favorite and classic environments, a driveway crack! If this specimen has not been sprayed, you might taste a few leaves -- people put it in salads. And if don't want it around, pull it now, it is about to bloom and the seeds will be abundant. $\endgroup$ – Bryan Hanson Jul 16 '18 at 23:47

This is Common purslane, Portulaca oleracea. It is used in salads, although it contains oxalic acid and there are poisenous plants resembling Purslane, see comment below. https://en.m.wikipedia.org/wiki/Portulaca_oleracea

    $\begingroup$ An acquaintance advised me of this: 1) Make sure you can distinguish it from hairy-stemmed spurge (which is poisonous) 2) Purslane contains oxalic acid, so those at risk of kidney stones should not eat too much!
