Creeping Phlox question
I have some type of Phlox (pink) in the rocks of my stone wall and some on the top. It is very pretty as it hangs down. I would like this to spread all along the top of the wall as well. Can I do this with what is already ther (replant it)If so, how would I do this? or do I need to purchase more of this type of phlox?
