Don't see why not, I think they aren't the fussiest of plants. If your soil is extremely heavy, try breaking it up a little by adding some general compost and mixing in? You can divide the clump later if you want to. I think phloxes are lovely.

Phlox subulata is going to want a fast-draining, sandy soil, however.

Drat! I wish I knew how to withdraw a stupid comment I made!

creeping jenny is very efective or natural stone cemented just hanging over the edge works well to.

Thanks for your responses.
