Steve,
my wife and I between jobs used to fix up houses....once the house work/jobs were done we always built those kinda structures...love seats etc.....some very big, well big enough to cover our 6m caravan......
She grew Clematis mostley over them but we never got to see it in full bloom as it were.....
we'd ususlly sold......hahaha.....
In France we did the same thing......but in 16 years the Clematis never really took hold.....
U guessed it until we put it up for sale.....I know it helped a lot....Clematis, Montana Rubins.....
Now were a lot further south we are planting climbing Jasmin and Bouganvillia instead.....
Nicest thing tho, the Jasmin is night sented.....
also here we use a lot of cactus and other drought loving plants...Geraniums the size of a bushes.....
we do have a couple of decent beds next to the house with Dhalias and other stuff, I have no idea what but they now have automatic irregation.....
I was always lacking in garden design, I'd find somebody to help with that....I just love a well laid out garden....
So along with ur Airendack chairs it will look great.....
lastley, I kept a peice of me dads Rhubarb for years but I'm sure it got sick of moving house.....sure miss proper crumble but the belly size dont....hahaha...
