Maybe here's the place to bring up my confusion over variety vs. forma. The differences are so subtle botanically but often not subtle at all horticulturally.

When is a plant a var. or f. versus "natural variability" and therefor neither?
I go with the flow but I still feel this is one significant flaw in the crossover from botanical to horticultural databases.
