Housed at the Fort Worth Botanic Garden is the largest collection of begonias in North America—and one of the top in the world! I had the pleasure of taking a behind-the-scenes tour with one of the foremost begonia experts, Don Miller, (who also happens to have a begonia named after him!) The working greenhouse and the collection greenhouse at Fort Worth are not open to the public except by scheduled tour. To schedule a tour, you can call the information desk at (817) 392-5510.
