What about horticultural significance?
The plants found in a typical postwar suburban garden will be quite different to those grown today. It may not matter quite as much as feeding the third world but it's probably more important than some things our local council has spent money on lately. Having studied horticulture I can get a little cross when I watch a historical drama set in Elizabethan England and see a vast rhododendron shrub in shot. So if the National Trust want to get these things right they need to investigate. It's probably a lot easier to do Paul's old house and garden, thanks to Mike's fab photos.
;sorryJust a personal thing, let's get back to talking about Yoko's sunglasses and Ringo's underpants.
