For twenty-two years, conservation scientists in New Jersey watched the same slow-motion ecological crime play out every spring.
Garden centers across the state would roll out flats of Bradford pear, Japanese barberry, Norway maple, callery pear, burning bush, English ivy, multiflora rose, Japanese stiltgrass — plant after plant after plant on the state's known invasive species lists, sold to homeowners with no warning that what they were taking home would escape their property and degrade the surrounding forest within a decade.
New Jersey was one of the only states in the country that had no law to stop this. On January 20, 2026 — Governor Phil Murphy's last day in office — that finally changed. Murphy signed the New Jersey Invasive Species Management Act (S1029/A4137) into law, establishing a permanent statewide framework governing how designated invasive plant species can be grown, sold, distributed, imported, exported, and propagated in the state.
The law creates a 19-member New Jersey Invasive Species Council comprising experts from state agencies, environmental organizations, and industry, charged with developing and maintaining a science-based list of prohibited invasive species.
Implementation is phased. Thirteen months after enactment, individuals will be prohibited from propagating, importing, or introducing listed invasive species without obtaining a conditional use waiver from the Department of Environmental Protection.
After 49 months, the restriction expands to cover sale, distribution, export, and offering of these species. Nurseries get time to manage existing inventory and shift production toward natives and non-invasive alternatives — a critical concession that brought the New Jersey Nursery and Landscape Association on board as a partner rather than an opponent. The bill ultimately passed the Senate 39-0.
The 22-year backstory matters. The Invasive Species Council was originally established under Governor Corzine in 2004.
Senator Linda Greenstein sponsored failed bills in 2018 and again in 2022-2023. Murphy vetoed an earlier version in January 2024 over regulatory coordination concerns. Conservation groups — New Jersey Audubon, the Native Plant Society of New Jersey, Friends of Hopewell Valley Open Space Invasive Species Strike Team, and dozens of others — kept pushing.
Industry partners like Pinelands Nursery helped bridge the conservation-commercial divide. What's actually being protected is the spring forest floor of New Jersey: the trillium and bluebells and trout lilies that emerge before the canopy closes, and that have been steadily displaced for decades by aggressive invasives that smother them out.
After 22 years, those native woodland wildflowers finally have legal backup.
