Hi Kathleen:

Our experience at CBG strongly suggests that invasiveness is very much a
regional characteristic. For instance in the Chicago area Buckthorn is
invasive but in other regions experiencing a zone 5 climate it is not
invasive. In other words, the ability to invade is based upon a complex
interaction of environmental factors, not simply minimum winter

"As a general guideline, if a particular species is a weed somewhere in
world, growing in the same hardiness zone you garden in, be very wary  
of introducing it to your garden."
