Ooooh I'm always in awe of people who make clicker games as the number stuff hurts my brain haha, that being said I'm a total Idle-Clicker game addict so I'm excited for this one!
As for suggestions;
If you're sticking to reality I'd say maybe having options for plants you grow close by which give off different levels of pollen as "buildings"
If you're going silly then Bee GPS, and where Bees have worker drones, you should be able to buy Drones that do the job of bees :D
