My backyard paths used to be Saint Augustine grass but have all been replaced with mulch. Not only is it easier to maintain but it cuts down on watering as well. A patch of Oxalis seeded itself in one of the beds and I liked its look. I decided to let it spread on its own. It decided however to jump the bed into the paths. I realized it looked better in the paths than in the bed and transplanted all of it. It is now spreading nicely and needs no up keep. It gives me green paths without the burden. Now, as it spreads, I'll need to make sure it doesn't spread into the rest of the garden!
