Alternatives to NYS Invasive Prohibited Plants

Alternatives to NYS Invasive Regulated Plants

Invasive species are among the top causes of biodiversity loss across the globe. New York is one of many states throughout the U.S. now taking steps toward improving our environment by slowing the spread of invasive plants. Horticulturalists and gardeners can be part of the solution by growing and planting alternatives to ornamental invasive plants.

Here you’ll find plants similar both in appearance and in cultural requirements to the invasive plants they can replace. These plants may be native or not but are not considered invasive. The alternatives listed here are just a few of many possibilities. They are hardy in much of New York, but check both your hardiness zone and your site’s conditions. Many of these alternatives are readily available at local nurseries.

Invasive plants and animals pose a serious threat to some local economies in NY. For one, maintaining the value and beauty of woodlands, parks, and farms requires expensive control measures. For another, invasives that diminish the natural beauty of the outdoors also diminish the value of tourism.

You can help make the future of New York greener by growing the “native-friendly” plants suggested in this brochure instead of invasive species.

Seek additional advice at your local extension office and through Cornell’s searchable Woody Plants Database.

Please see the New York State Department of Environmental Conservation (NYS DEC) regulations and the complete list of prohibited and regulated species. Check local laws, as some NY municipalities have further restrictions on invasive species.

Alternatives to NYS Invasive Prohibited Plants

The NYS DEC prohibited plant list consists of 69 invasive plants. As of March 2015, it is illegal to sell, import, purchase, transport, propagate or introduce any prohibited invasive species. Most of the prohibited plants are considered weeds. Listed here are selected prohibited and regulated plants that have ornamental characteristics and are sometimes cultivated.
