LOL that's where 90% of mine have come from. Most recently, Last week a member from Washington state sent me a Raja Puri and it got here in under a week. With tropical plant or banana plant on the customs form every time. People get too scared easily.
DO NOT try to ship lives plants across the border, there's a good chance you will lose it in customs. If you do happen to cross the border, you can legally bring in bananas (they're considered houseplants according to the Canadian Food Inspection Agency) as long as the plant is not too big - it must look like a houseplant - and you declare it. If you don't declare and get caught you get big trouble.
