"take a bunch of flowers they grow in the ground for free"
Would you care to elaborate on that. How is growing them in the ground free? Remember your explanation needs to cover the fact that if the flowers weren't being grown something else would be. It also needs to explain how the flowers are grown with zero effort in propagating, ground preparation, planting, weeding, pest control and harvesting. It also needs to explain how the flowers got to be looking pretty without any cost, given that it will have taken generations of careful hybridisation and selection to get them to that state.
Have you ever actually tried growing flowers or anything else?
