Maybe you could get some ideas from this website I ran across; there's a photo search (only 1115 pix for the 1433 cultivars listed
) by color and/or leaf shape.

For what it's worth, leaf info would be useful in the general info area as well. I grow many plants as much (or more) for the foliage than the flowers.
