I've planted a row of lavender at the top of a retaining wall. It's in full sun and the soil drains well. The lavender is growing nicely and I think it's time to add a nice trailing plant to hang over the wall. I'd like something evergreen if possible (in zone 7b) and I think Creeping Jenny is really pretty.

Do you think it would interfere too much with my lavender? I don't want to choose a plant that will hurt it!
