I need to cover an south-facing slope (gentle - 20%?) that's about 90 feet east/west, 12 feet north/south - it lies between a stone retaining wall (to the north) and a gravel road (to the south). I'm looking for something that will grow dense and choke out weeds, but ideally also be beneficial to wildlife and/or aesthetically appealing.
I'd really like the groundcover to be native to northern New England. Candidates so far (and apologies I don't have the Latin names) are bearberry, bunchberry, checkerberry (creeping wintergreen), and lowbush blueberry. However most of these seem to be acid-loving plants, while I think my area is more neutral. (Also, I know that juniper is another option, but I've never been a fan of juniper, and it seems to do nothing other than sit there... no color, no berries for humans or wildlife, etc.)
Any ideas welcome!
