I have found "The Fairy" to be a wild looking rose that keeps a nice small habit. In my case I have kept it in a pot. It got about 2ft wide and about 1ft tall, with blooming branches multiple flowers open on each one (fern like) for months. (It also recieved first place for pink miniture at my state fair) Wild roses up in Alaska seem to have a lovely arching branch habit and this rose matches that.

good luck

"The Fairy" is a Polyantha, and some of the roses in that class may have the characteristics that you seek (small, full blooms, very bushy habit).

Here are more suggestions: Suggestions for mini w/o stamens showing or quilled petals?.
