You couldn't go by that. For example, there are tiny alpine Centaurea species that will never invade anything, but that are grown by a few rock gardeners; but no one would suggest that the entire genus is safe. (Probably all the invasive ones are already here, however.) Are there any weedy >carnivorous plants? Weedy Tecophiliaceae. ? etc. Oddly enough, the carnivorous North American species Sarracenia purpurea has been the subject of concern after being introduced to one or more bogs in Britain. I don't know if it's really "weedy" or if this is just an extremist view. It can form pretty dense colonies in its native habitat, though. Anybody who likes to grow non-native plants and is also contributing to the Natural Resources Defense Fund should become familiar with that organization's stance on exotic plants, which I regard as extreme. Regarding databases, I keep one on my bulbs, but this tells me I need to go around and make an updated list of the trees, shrubs, and perennials here. I'd need it anyway once I put the place up for sale, since I'm hoping to attract gardeners instead of somebody who'll clearcut and bulldoze the whole place to plant Christmas trees.
