I noticed a couple of wild plants by my grill and decided to see if I could make my first park. I expected I might need to relocate my grill, but to my surprise it actually complained about there not being enough plants. Is the Briar not a plant? The Mealwood? Or is the grill the problem and the tooltip is misleading me?
Build a small room around a Briar, Mealwood, Park Sign, and Electric Grill. Check the tooltip.
