Some shrubs that are fast growers are too good at what they do. Dubbed "invasive" shrubs, these are the cheaters: their progeny tends to escape cultivation and exploit an unfair advantage to out-compete native species.
The following plants, popular because they are fast growers, are deemed invasive shrubs in North America:
Burning Bush: Fast Growers, Invasive Shrubs

Barberry: Fast Growers, Invasive Shrubs
As widely despised as an invasive shrub as burning bush is, I have more of a bone to pick with barberry, myself.

Privet: Fast Growers, Invasive Shrubs
Here's another plant whose inclusion here among invasive shrubs may strike some as odd. What's more familiar than a privet hedge? If I were writing a dictionary entry for "privacy hedge," I might well accompany it with a picture of privet. In this case, familiarity breeds not contempt, but acceptance; yet this fast grower is, indeed, considered an invasive shrub in North America. To learn more about privet, click the link below:
