Invasive plants are second only to urban sprawl in destroying rare and endangered species habitats.

Knowlegable gardeners are keenly aware of their influence on the environment and should not be promoting the use of these species.

Gardens Are... actively participates in the education of consumers and industry professionals about invasives and their alternatives.

The Massachusetts Division of Fisheries & Wildlife created A Guide to Invasive Plants in Massachusetts to introduce residents to species that are, or may be potentially harmful to the biodiversity of our environment. The entire book is available in .pdf or .zip.

Native Alternatives for Invasive Ornamental Plant Species, edited by Timothy M. Abbey is another book that features five of the invasive plants which are commercially available. The native plants are listed with information on their flowering time and color, light and soil requirements, size, wildlife benefits, and suitability for various plantings.
