Updates to the Massachusetts Prohibited Plant List

Posted in: News

The Massachusetts Prohibited Plant List has been updated as of December 8, 2025 to include three additional species (see below). Species on this list are banned from sale. This ban covers purchase, import, propagation, and related activities, and includes all cultivars, varieties and hybrids of the species listed.

There will be a phase-out period for these newly listed species, so that Massachusetts nurseries and agents can sell off existing stock that was received or propagated before December 8, 2025. The schedule for this phase-out is listed below:

Common Name	Scientific Name	Deadline for import/ propagation	Deadline for all sales
Black alder, European alder	Alnus glutinosa	12/8/2025	12/31/2028
Chinese silver grass, Eulalia, maiden grass	Miscanthus sinensis	12/8/2025	12/31/2026
Jetbead, white Kerria, jetberry bush	Rhodotypos scandens	12/8/2025	12/31/2027

Imports of these species from out-of-state growers or sellers are prohibited as of December 8, 2025 – there is no phase-out period for imports.
