Ortho GroundClear Vegetation Killer contains two active ingredients, glyphosate for post-emergent plant control and imazapyr for long-term pre-emergent treatment. This product will affect any plants that you spray with it, but it can also kill plants if their roots contact treated soil. Since this product is designed to last in the soil for many months, you should not spray it where there would be any contact or runoff with the root systems of desirable plants.
