As a child I remember Purslane as a weed to be hoed out of the corn fields, as an adult I remember it as a weed to be pulled out of the lawn before it takes over everything. Then one year I bought some ornamental Portulaca from Lowe's, my wife and I both loved it. It only lasted a very short while, the squirrels loved it even more and devoured it in a matter of days. We have never seen another Portulaca locally as lovely as that. We will be looking again this year!
