Jason,
I've been interested in the Scarlet Bristle for quite a while. I might want two or three. I have an import permit for small lots of seed from Canada, but I don't have a permit for plants. I could get one - it will take a few weeks to process.
Or, if you prefer, you could get one. You'll have to show up in person at a USDA office to show ID, one time only.

There's no guarantee that the USDA will allow the plants into the country, but perhaps Keehn's Carnivores has some experience shipping plants to the U.S.
