The drive around the rim is 33 miles of winding, up and down mountain sides, skinny little roads, but the pull outs were often and we stopped for all the sights. We even stopped for a little lunch in a very cozy little picnic area. There wasn't much for ground cover, a lot of the pinkish red leafy plants, a little of the green with with purple floweres, and a little of the small yellow flowers. There were a lot of trees, however.
