I had wondered about that species being listed. I grew it here in 
Oregon and though I had to control its seeding, some of my friends 
who were gardening on more poorly drained sites couldn't keep it alive.

The really crazy one is that Oregon lists, among "potential 
invasives," Cyclamen coum. It is less enthusiastic here than C. 
hederifolium, but I imagine someone saw the famous colony of it at 
Boyd Kline's garden in southern Oregon and "totally freaked out."

where we have only a little sleet and ice at the margin of what just 
covered Bob's Denver garden in masses of snow.
