Massachusetts: invasive & noxious plant laws
The Massachusetts Department of Agricultural Resources (MDAR) prohibits the sale, import, trade, purchase, distribution, propagation and related activities for every plant on the Massachusetts Prohibited Plant List, including all cultivars, varieties and hybrids. Newly added species get a phase-out: nurseries may no longer import or begin propagating them, and existing stock may be sold until a deadline (1 year for herbaceous plants, 2 for shrubs, 3 for trees). This page transcribes MDAR's list (151 entries, CSV dated May 2026; page last updated February 27, 2026).
