RICHMOND, Va. — Thirteen more species that pose a threat to the state’s ecosystems have been added to the Virginia Invasive Plant Species List. 

The additions include Italian arum (Arum italicum), nandina (Nandina domesticum) and orange-eye butterfly-bush (Buddleja davidii)... 

Invasive plants are a menace. Here’s how to avoid them in your garden. What to know to avoid buying invasive plants and how to manage them if you have them already. If you walk through your yard, what do you see? Are there vines dripping with long clusters of light purple flowers?

Study finds plant nurseries are exacerbating the climate-driven spread of 80% of invasive species. New research from the University of Massachusetts Amherst is the first to precisely map role of horticulture in spreading invasives, projecting ranges under 2° Celsius of warming.

Invasive plants are still for sale as garden ornamentals, research shows. 1,330 nurseries, garden centers and online retailers are still offering hundreds of invasive plant species as ornamental garden plants. This includes 20 species that are illegal to grow or sell nationwide.
