The Denver Botanic Gardens has a tropical rainforest pavilion. I, on a mission, went to see Dale Chihuly’s installations, but found the “Ants and Plants” wonderful. You probably know that “symbiosis” means “together + life”. A common example is of orchids clinging to trees for dear life. But there are types of “mutualism” that benefit both, like ants and plants. Ants burrow into plant stems for shelter, and the plants benefit from nourishment (droppings), cleaning, disbursement, and defense. Wow, like healthy families, parents and children, partners, spouses. We need each other.
