want a groundcover for a hill
We want to put a groundcover for a hill that we'd rather not mow. Any suggestions? Here's what we'd like
1.will crowd out the grass that's there now.
2.Will stick around in winter to keep the hill from eroding (even it it's all dried out).
3. Will spread, but hopefully will still be "controllable."
The hill is protected from wind, so I'm not too worried about wind damage.
Also, I was wondering if we could plant anything this time of year, or should we wait until spring?
Thanks for your help.
