Hello. We have a 2m high wooden frame / pergola / awning to the north and west sides of our house. Please see photos. Wisteria used to grow there but we have cut it down to prevent its roots from drying out the reactive clay under our foundations. Can you please recommend a less invasive type of climbers we can grow in pots suitable for our wooden frame that will provide shade and privacy with roots that stay in their pots? Ideally the climber type on the north side sheds in winter to allow light while the climber type on the west side is ever green to block the setting sun and for privacy. Ideally they flower too. What size and type of pot should we use? Can we place the pot on a porous stone surface or paver so that the roots don’t grow out of the pot through the drainage hole? Would sandstone or bluestone pavers work or something else? Many thanks in advance.
