As a side hobby, I grow Nepenthes (Tropical Pitcher Plants)

In the above link are some pictures of the plants I bought from the US and drove them across the border. Further down in the thread, there are links and discussions about directive D-08-04 by the Canadian Food Inspection Agency.

which allows hobbyists or homeowners to bring up to 50 houseplants across the border yourself-for your own use to be grown indoors.
If you are interested in this, contact me because I do drive down US side to pickup items on a regular basis from my mailing outlet. I should be going down again within the next couple weeks.
