Thank your for suggesting moss phlox. I have a small amount of moss phlox in a sun/shade garden, where it is very happy and beautiful. If it will grow that well in a sunnier setting, that would be ideal.My new shrub border can be hot and drought-prone, although thankfully that has not been a problem in 2015. Moss phlox is described as drought-resistant, so I am very hopeful. After reading about it, I conclude that spring is the time to plant it, so I think that I will wait until then.
I have never seen creeping jenny, although I will certainly look for it.
I found the Steppables website very interesting and useful information. Thanks for telling me about it. It contains very helpful snippets of information about creeping jenny but nothing that I could find about moss phlox, unless I was looking in the wrong place.
Thanks to both of you for your helpful replies!
