Trivial Misc. botany bugs

[amaranthineApocalypse]

What the title says (no pun intended):

• Bees don't make honey (worst one imo   )
  
• Free-range eggplants don't give seeds
  
• Coffee beans' potency doesn't affect the reagent amount
  
• Bamboo stalks dissapear when cut
  

Feel free to add more

I'm going to take this opportunity to grump about how you can't chain reagents through hybridisation and mutations again.
