Invasive lists, was Sharing seeds of rare plants

Take, for example, state governments, and, in particular, the
Colorado Department of Agriculture. Euphorbia myrsinites is listed
as a noxious weed. (You can see it growing along the road in one or
two places.) Whose idea was it to list it? I doubt that anyone in
the CDoA has the inclination to drive around the state looking for
"invasive exotics" to include on their list (for the purpose of,
say, increasing their power and authority). Undoubtedly, someone saw
the euphorbia, totally freaked out, and contacted the CDoA.

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."
