"Spring's stinkiest tree" remains legal in Canada, despite US bans

Often called “spring’s stinkiest tree” due to its rotting fish-like smell, the Bradford pear is a fast-growing ornamental known for its white spring blossoms… and the headaches it can bring. To date, officials have banned the invasive tree in four states. New Jersey is the most recent adoptee of the law, announcing earlier this month that the “propagation, sale, and distribution” of the tree could result in a $2,000 fine.

Despite restrictions south of the border, the Bradford pear tree remains available for purchase at garden centres across Canada, even though it is a recognized invasive.

Restrictions on the Bradford pear tree stem from concerns over its spread into natural areas and high costs associated with removal. Warmer climates in parts of the U.S. fuel the tree’s spread and growth: In some places, it can reach up to 15 metres in height.

Early in the season, the trees can create dense canopies that can result in “dead zones” that block out the light other plants need to survive. Spread and growth are more limited in Canada due to our cooler temperatures and shorter growing season.
