I've got a long narrow strip of flower bed that runs alongside my drive. I have climbing roses growing happily on wires on the fence there, but am struggling with what to plant at low level. It gets a lot of sun but is quite exposed. I tried French lavender and it was a dismal failure. English lavender in a nearby bed (at right-angles and a bit more sheltered by the house) seems to love it, so if all else fails I could have more of that, but wondered if others had more creative ideas?
