Evergreen Gardenworks - I stumbled onto this source for affordable Bonsai material because I was looking for Bald Cypress. They have the classic material specialized for Bonsai trees. If you want something more exotic, like Jaboticaba, you will have to look somewhere else. If you join a Bonsai club, they can point you to many great sources for Bonsai material. You can also get great material at your local garden center. I have many, many choices for that on this board!
