African violet leaves come in many shapes and sizes. It's good to have a handy reference nearby so that when you're trying to order violets or are thinking of adding to your collection you can be more confident of what will actually show up at your doorstep.
These are some illustrations from the TAVS, which I believe is the Toranto African Violet Society. If I'm mistaken, please contact me for a correction.
