Orchid Month

Marjorie Merriweather Post had a lifelong love affair with orchids, her favorite flower, investing significant resources into fueling this passion. Today, Hillwood's collection contains over 2,000 orchids of approximately 1,200 different species, hybrids, and clones. 

As one of the only public gardens in Washington, D.C. that offers daily access to a working greenhouse filled with orchids, our month-long focus on these exotic beauties features workshops, tours, and colorful displays. Scroll down to learn more.
