upat5 - thank you for your clarification. Your post suggested to me that you resented property-line-crossing measures to control invasive problems at the same time you were contemplating allowing the reverse to be visited upon your neighbors, a very uneven-handed position. Since you say that is not the case, I apologize. Please don't forsake this venue on my account, and I applaud your efforts to restore native flora to your property. Your additional posts make it clear that you have made the effort to educate yourself on the problem invasive species in your area and are applying that knowledge. The action I would take issue with is intentionally allowing your Canada Thistle to go to seed. Apparently I misunderstood your intent. I wish you the best of luck on your efforts. Again, please don't go.
P.S. Solidago canadensis is indeed Canadian, and American, and Mexican. It is native to most of North America and was first identified as a species due to early botanical work in colonial Canada. Likewise, many widespread species have specific epithets of virginica, carolina, and pensylvanica because these areas were settled and studied early on.
