What to plant with/along side creeping phlox

Question

I live in Devon and have a double dry stone wall with planting area at top, it is an open area with lots of light. I am considering planting creeping phlox to cover top of wall and help keep weeds at bay, but as only flowers in spring I wondered if you can suggest something that will grow in harmony for summer colour, ideally evergreen and grow every year,

Answer 1

Periwinkle Vine would be lovely.

Here is an article that has information on care of this blooming vine!
