6 invasives species face ban: Michigan targets callery pear trees, Japanese barberry

LANSING, Mich. – Two popular ornamental plants often used by landscapers may become illegal to buy, sell or plant in the ground in Michigan – in addition to four other known invasive species.

Super-smelly callery pear trees and prickly Japanese barberry shrubs have been targeted for new regulations by state agricultural authorities because they have been wreaking havoc on Michigan’s forests. These invasive species stand to become restricted starting in January 2028, if top state officials approve.
