Rutgers Expert Warns Against Invasive Plant Species

Rutgers Cooperative Extension offers assistance in identifying and managing invasive plants while promoting native alternatives for healthier local ecosystems.

MORRIS COUNTY, NJ – In an effort to protect local ecological processes, Jean Epiphan, a Cooperative Extension Agent at Rutgers Cooperative Extension of Morris County, is cautioning homeowners against the unintended consequences of planting invasive species in their gardens and landscapes.

"Problem plants" may initially be difficult to identify as some are readily available for purchase. Epiphan suggests homeowners start by identifying the plants already growing in their yards. Invasive species are typically those that spread easily and are challenging to remove.

For assistance with identifying and managing these "green intruders", residents can reach out to the Rutgers Master Gardener of Morris County Helpline at 973-285-8305 or email rcehelpline@co.morris.nj.us. In addition to identification services, the cooperative extension provides information about native alternatives that support a healthier ecosystem.

One common invasive species is the Japanese knotweed (Polygonum cuspidatum syn. Fallopia japonica). Though aesthetically appealing as a yard accent, this plant is at the root of a growing problem. Like other invasive species, it can spread from personal gardens into broader natural areas, disrupting ecological processes.

Epiphan and her team at Rutgers urge homeowners to consider native species for their landscaping needs. To help residents in making informed choices, several resources are available:

For garden planning, the New Jersey Invasive Species Strike Team provides a comprehensive "Do Not Plant" list available at fohvos.info.
Rutgers has also published a fact sheet, FS1140: Incorporating Native Plants in Your Residential Landscape, available through Rutgers NJAES.
