I'm so amazed you were just able to bring live agricultural material over like that! The French aren't worried about invasive species or pests or things? Maybe because France already has mulberries?

I brought a tiny packet of fresh chile peppers back from Colombia and had to promise to eat them to let them pass. (But now I've saved and planted the seeds muahhahaahahaha so when American agriculture goes under due to an Amazonian pest, you can thank me)
