Tropical regions cover just 10 percent of land mass on Earth, but contain over half of all plant and animal biodiversity. The tropical greenhouse at Lockerly represents this vital world region with an impressive display of orchids and tropical plants alike, including many fruit and spice plants. Our orchid collection, commissioned in 2017, includes over 60 orchids of over 50 varieties. Other tropical plants in this collection include citrus trees, pineapple plants, and stunning staghorn ferns. This collection is located just behind the Arboretum office and is wheelchair accessible.
