Trying to decide on a replacement specimen tree for an ornamental plum that is in decline and will be removed. Looking for suggestions for an ornamental cherry that is disease and insect resistant in the wet Lower Mainland BC climate, ideally with good fall colour, and hoping for a unique variety. I love a natural tree shape, (will not pollard or prune beyond removing crossing branches if need be), but it can't be too broad a spreader due to proximity to the house (@ 12' to nearest roof edge). Height is not an issue. Site is almost full sun, good air circulation, on amended clay that tends to stay quite wet in winter months. A fast grower would be ideal. Considering the following: Shirofugen (may be too broad in spread)? Okame Mt. Fuji Sargent Cherry Higan Cherry I am not terribly knowledgeable about ornamental cherries, (just learning), so any suggestions appreciated, thank you in advance.
