##### Nomenclature/History

The history of orchid growing dates back to the late 18th century when British horticulturist became fascinated with these plants. At that time, many ships were sent to explore the tropics. Among the discoveries were many orchids that were quite different from the native European forms. Soon, wealthy plant collectors commissioned explorers to gather orchids from tropical and subtropical areas. These plants were then boxed and sent back to Europe where a large demand was created and plants were sold for high prices. Only the hardiest plants survived the long trip back in crates. Once they arrived, growers put them into dark, hot greenhouses which they believed mimicked the tropical conditions where they were collected. Few plants survived these growing conditions which added to the fascination and mystery of these plants. Knowledge about growing orchids became closely guarded secrets and only the wealthy, who could afford greenhouses, were able to fully enjoy the diversity of this plant family.
