I found these great pdfs on Don Schmid nursery. They have great information on each variety with several photos. The full book (389 pages) has everything or you can check out trees by categories like upright, dwarf, variegated...ect Many show examples of mature trees. Definitely worth checking out! This is Don's life work, I presume because it would take a lifetime to collect all these great photos and detailed information comprised from his experience growing the varieties (and not the typical recycled descriptions) Don Schmidt Nursery | Maple Books Maple Books Check out our full Maple Book: Full Book (33MB) or download a single variety: Dwarf (8MB) | Lace Leaf (4MB) | Trial (7MB) |Upright (12MB) | Variegated (3MB) You can also view our Online Plant List to see our selection.
