I spent a very wet Friday afternoon at Hollander's Tiny Tree Farm in Chrisney, Indiana.  Greg Hollander grows many different varieties for pre-bonsai material.  He advertises Corkbark Elms, Seju Elms, Trident and Japanese Maples, Japanese Black Pines, Shimpaku Junipers, Bald Cypress,  and many more.

While at Greg's I picked up 3 good sized Parson's Juniper for bonsai.  Juniperus davurica expansa (Parson's Juniper) is a low growing scale juniper that is a great subject for bonsai.  I'll be documenting their progress over the next year on this bonsai blog.

Depending on the weight of your right foot Hollander's Tiny Tree Farm is just a little more than an hour outside of Louisville.  Make it a point to visit him this Spring if you find yourself in the area.
