Hedge/screen for foliage or flowers

Hedge would be on north side of it so not a problem.
Sweet peas - will have two good long rows of them elsewhere.
Love the idea of a camellia hedge. Would screen the cage and look good all year round. No good for picking, flowers fade really quickly, but not worried about that.
Also like the idea of pittosporum …. I’ve got a couple of small pot bound “Tom Thumb” that I’ve had for about twelve months that need planting out, and the foliage would be really good for picking.
Also wondering about eucalyptus…. I’ve got a couple of small pot bound ones from yet another impulse buy a while back. Lots to think about.
Thanks for suggestions Veggie.
