The San Diego Zoo is home to several critically endangered species, and not just animals. We’re talking about plants, too! This week, hosts Rick and Marco speak with Zoo Horticulture Manager Christy Powell and Senior Plant Propagator Heinfried Block about orchids. You can find orchids on every continent except Antarctica, however conditions need to be just right—including having a special fungus around. Find out how our team is saving, protecting, and caring for orchids, the importance of symbiosis, and how you can visit the Orchid House.
