I don't, but have you thought about something like a caning type shrub? I have a sloped yard and the previous owner planted terraces of snowberry, it has held up the ground very nicely and fills in like crazy (too much, unfortunately). We have clay soil as well. I would definitely look at vinca minor and some of the spreading sedums. You will want to consider at least a few evergreen plants in my opinion.

I'm surprised you lost the crown vetch. In my area, this is a pretty invasive plant and pretty tough to kill. Then again, I, too have tried to get a bank of them going, and they seem to grow everywhere BUT where I want them to. That being said, these are a pretty tough plant with roots that really run and will take over an area fairly quickly. I think the key to your problem is the acidic soil. The hill area you describe is pretty big..otherwise I'd suggest trying some rhododendrons and azaleas. The wind might be pretty tough on them though. How about pachysandra as a ground cover??? I intensely dislike this plant, since it IS an incredibly prolific groundcover that will virtually choke out anything else in it's path. So, if you want it, know that you will also not grow anything else there. It MAY well be what you're looking for. It is truly an indestructible plant - actually a nice looking, non-blooming, green groundcover that puts out lateral roots like there's no tomorrow. Hope this suggestion helps. You could probably do it yourself..just get a good number of plants, space them out, and it probably won't take that long until they take root and take off. Best, Keith

I think this would do it. To some people this is a scourge, but for your purposes it will work. I used to grow a patch of this and it was as tough as nails. You should kill the existing grass first though. Any seed would have a hard time getting established through grass. English Ivy would be another alternative. It's pretty tough and grows quickly. I'd start with transplants though.

Definitely a bane. Here's a list of native plants for NM, some specifically state that they are good for erosion control. http://www.plantnative.org/rpl-az.htm Also, you might want to contact NM State Forestry Division for some advice and/or assistance.
