I have a spot facing South in Kitsilano that is not very large where I would like to put a tree-like plant (ie. it could be under-planted) in the area. The light is sun to partial sun as we have a huge cedar further south, the house and a fence which all block the sun at different times of the day. The height has to be less than 8' and as I want it taller than wide that limits its size. I want a fairly open plant, not congested, twiggy. Flowering, fragrance though not a stopper. Maybe standards would be good? Any suggestions?
