She's not fine with having seeds sent to your home, but completely fine with you growing within that same home? I may be missing something.

Speaking from experience, if the seeds are sent internationally, only a general customs letter will be sent to your home if they are seized. If sent domestically, a knock from the secret service or USPS police may be at your door.

As stinky said, the best way would be through a friend or saving good bag seeds. Setting up a PO Box is a very simple and cheap alternative as well.
