Butterfly Bush

A List of Common Exotic Invasive Plants

Butterfly Bush (Buddleia spp, probably Davidii)
Butterfly Bush (Buddleia spp, probably Davidii) provides nectar but that’s all.

Invasive exotic plants are plants that are not indigenous to an area but nevertheless have established themselves and reproduced. Not being indigenous to an area, the plants have no natural predators or diseases. This freedom from predators and diseases, enables the exotic plants to spread unchecked.

Exotic invasive plants run rampant and inhabit space that native plants normally would. Native indigenous plants which feed native indigenous insects and other animals are overwhelmed by the exotics. The food sources of native indigenous insects and other animals disappear.

No native indigenous plants = no native indigenous insects, butterflies or beetles.

The United States Government defines an invasive species as:

“An “invasive species” is defined as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.” Executive Order 13112, 1999 (signed by President Clinton, which established the Invasive Species Council).

This list of invasive plants was copied from the “Invasive Exotic Plant Tutorial” on  the Department of Natural Resources. http://www.dcnr.state.pa.us/forestry/invasivetutorial/List.htm

Watch List (16)

These are species that are known to be widespread problems in
other Mid-Atlantic states and have recently been reported, by experienced field
botanists and a recent DCNR Survey conducted for State Parks and State Forests,
as being established in some natural areas in PA. In addition, some of these
species are significant problems in adjacent states and appear to be ‘on the
move’ towards PA. Contact DCNR – Bureau of Forestry for assistance if you are
dealing with a species that we have not included in this list.
