Q.Will Creeping Jenny Choke Out Existing Plants?
We moved into a new home and ground is rocky and not conducive to grass.(fairly steep slop on one side) This is where I would like to try creeping jenny. I have planted some hostas and ferns there. But would like a ground cover to help with erosion. Would this work?

Creeping jenny is often recommended as a groundcover. It can be invasive, but I do not think it will choke out your hostas and ferns. Here are more ideas:
