As my lawn was slowly dying in the summer heat, significant pieces of it were taken over by what appears to be spotted spurge. It is identified in various garden libraries as a weed pest and there appears to be a goodly industry devoted to killing it. I kept ripping it out, and it kept coming back. Incredibly drought tolerant! Not an unattractive plant, with little flowers. After a while, I decided that it wasn't a bad protector for the soil, in the absence of grass, so I left it there. While the grass will probably come back in those spots, I'm looking for other ways to use this fairly remarkable plant. Are there any good strategies? It hugs the ground, and probably won't like being walked on, but maybe in pots, draped over the perimeters?
