Hello and welcome to the vine Doctor!
I swapped seeds with someone in Canada and similar concerns were voiced in the thread which you can read in Seed Swap - titled Newbie from Canada - thread started by Manicorganic - sorry, I can't get the thread title to paste as a link.
The upshot is basically, American seed is controlled much the same way ours is and so long as you send full packets of seed and declare on the customs form that it is flower or veg seeds there is little or no problem. I got seeds from Canada and sent poppy seeds to Manicorganic. |
