Sorry, no picture. The plant /weed has soft red stems, grows in a flat tight mat. The leaves are opposed on stem and they are round to ovate. When it is time to flower, it has very tiny white flowers. It is easy to pull up but I have decided to leave this growing as a ground cover on my rocky area so no more tall weeds will take over. Is this a safe idea or am I all wrong? Please identify this and give me some kind of idea what I'm in for.
