Did you know the Bunchberry Dogwood plant has a built-in trebuchet? Its complex catapult-like features compare to the propelling leverage launchers of the Middle Ages.
The North-American Bunchberry stands only one-tenth of an inch tall, so it needs to send its pollen up and out! To catapult its pollen, bunchberry flower petals open, each petal is separated and flipped backwards, almost immediately the stamen unfurls, blasting pollen into the air, sending it off to pollinate other bunchberries.
This process triggers the pollen to be launched up to 2,400 times the force of gravity!
