Davidia from seed Tetley?
I probably haven't got time for that
Clematis might do OK if I find a smallish one. I wondered about Eccremocarpus, I think it would cope better with the soil. Clems always look a bit depressed here
Lou if you get the right euonymus they have little clingy roots like ivy. E. fortunei var radicans, though that might be out of date as a name, the radicans is about rooting stems. Emerald and Gold etc are cultivars
