Along the edge
One of my raised beds is constructed from cement blocks (some dragged up from the beach...my sister's idea!). I've tried various things in the holes around the edge...summer savory, dill, marigolds. Two days ago, I bought some lobelia that was greatly reduced in price (peanuts really), planted them in most of the holes as a border...I like the way they almost glow against the concrete.
