This is what took me to The Scott Arboretum in Swarthmore, PA last weekend – their lecture+tour about the exciting subject of lawn replacement. We were shown 8 examples of alternative groundcovers around the campus and they’re displayed for your comment on my blog.
If you’ve had any experience with these – or others – tell us in a comment. Also if you know of good sources. This stuff’s a lot more expensive than turfgrass, so delawning homeowners need all the help they can get.
