Cattleya Orchids (Corsage Orchids or Queen of Orchids) are among the most popular and easy-to-grow orchids. Epiphytes (growing on trees) or lithophytes (growing on rocks), they grow from pseudobulbs which are food and water-storage organs. Native to Central and South America, they include about 50 species and numerous hybrids in a variety of colors. They are divided into two groups, the unifoliates, which have one leaf and large flowers, and the bifoliates, which have two leaves per stem and smaller flowers. Both types are very fragrant with showy flowers appearing on naked stems and lasting 4-8 weeks.
