Adding height to these terraced beds
I'm looking to add some plants with height to these beds to compliment the existing planting. The decked area gets midday sun (it's running N-S basically) and gets shade from a hedge on the right and the screen on the left. Clay flinty soil.
On the other side of the screen I've just planted Clematis, so I'm not sure if I want another climber on this side.
I've also got a couple of very small Acers that I have eventually earmarked for here. They're currently growing very slowly in pots 😊
Really I want to get some height in. Initially I'd thought about tall perennials but I'm wondering if some small shrubs would be better?
Any sort of help much appreciated.
I’ve no idea what I’m doing.
