Plant suggstions for a slope
I have a steep slope in the front part of my lawn that can't be mowed with a mower. I use a weed whacker. I want to plant at least part of it. It is about 10 feet down and about 40 feet across and the bottom is a storm drain ditch. I would want the plants to be carefree, dense enough to require little weed control or other planting. and not grow much above feet. I have a limited budget and often transplant from the wild.

Would that be in full sun, part shade or primarily shade?
Full sun. I'm so sorry I neglected to include that.
Some suggestions for that area could include our native Creeping phlox, Green and Gold (Chrysogonum virginianum) and Tiarella (Foamflower). You could also consider a bank of Black-eyed Susans and Sedum.
You could start small and just convert part of it at a time. For the first couple of years or so you should expect that there will be some maintenance, particularly weeding.
