I have a flamingo box elder on my recently purchased property that looks as if it was recently planted. Is this tree invasive, does it have pests, should it be left in or removed? Any comments?
Flamingo box elder – Acer negundo ‘Flamingo’ also Manitoba maple, western box elder, ashleaf maple. Flamingo is a cultivar, that has variegated foliage, the new leaves being pink so can be considered attractive. No conclusive proof that this tree is invasive. However, not on LEAF’s list of recommended trees for planting in Toronto nor the City of Toronto’s Urban Forestry website. This tree grows fast does have a tendancy to produce suckers. Can be prone to anthracnose, powdery mildew and canker. Insects can be a nuisance but don’t harm tree.
