I've grown Petrophytum caespitosum (Rock spirea) for four years in a half whiskey barrel. It's not demanding, however to get it to "crawl" it needs to be on the slightest slope on sandstone (preferred, since it crawls faster) or a limestone.

Here, in Utah, there are areas in some west desert cliffs where it grows in huge sheets that easily measure 6' wide x 10' long, welded to the cliffs. Surely worth growing!

You mean it can do with some Scotch whisky instead ;)
