G. PRUNUS (Mayday, Ornamental Cherry, Mountian Ash)
A long time favourite of ornamental urban tree design, prunus trees are beloved for their compact size, beautiful foliage, and low maintenance… but that’s unfortunately no longer the case for this troubled tree species. the reason: black knot fungus.

Being by far the most common tree disease we come across in Edmonton, any species susceptible to the disease should be avoided.
Typically considered one of Canadas greatest monument trees; silver maples unfortunately do not typically thrive in Edmontons climate.
Native to the the west coast, silver maples typically struggle with Edmonton winters, and rarely reach maturity. Although if they do survive to maturity, they tend to do fine.
Instead consider an Amur maple or one of various edible apple varieties instead. While the apple tree will bring a resplendent floral display to your landscape in the spring (and earn its keep with delicious fruit), the Amur offers brilliant red and orange foliage in the autumn.
