I would like to add things such as Buddleia Alternitfolia which is
really easy to maintain on one stem, just cutting out flowered branches
straight after flowering. I have this year had salvia uliginosa
flowering it's socks off, a plant you could just er, um, plant, and
then forget, also verbena bonariensis, suffering a bit of overkill from
it's popularity but good for screening.

Thanks, Janet. I have only recently discovered Buddleia alternifolia:
what a lovely alternative to davidii! My one concern in our daughter's
case is that she needs the screen even more in the winter than in the
summer...
