My neighbour's house is set back a lot further than mine, so when sitting on my rear patio, two-thirds of his house's side wall is visible. So I want an "instant" tree or shrub to partially screen it!
Ideal height would be about 12' with a spread of about 8-10', and an umbrella or fan shape to spread sideways to screen the wall. Can be deciduous or non-deciduous. Really want something quick-growing.
The tree or shrub would only be 9' from the corner of my house so naturally I'm concerned about planting a tree as I fear roots will undermine the house - unless it is a compact root. Firs have compact roots but they won’t provide enough screening.
My only thought was a buddleia as they are quick-growing and I can cut it to shape. Anyone got any ideas fro tree or shrub?
