That's cute, but plants that can be pollinated self-pollinate on day 9, so I guess if you like surprises, you just just plant lots of stuff, leave it alone and see what the bees give you?
Is that the idea?
People who cross, are doing it because they want a specific plant, are trying to get to a subsequent plant, or are trying for a mutant I would think.
Not sure what the bees would add, except randomness.
