If you have a greenhouse in which you can give cymbidiums cool nights and bright light, you should surely try a plant or two, for they are very handsome orchids. The plants have rounded pseudobulbs about the size of a fist, which bear eight to twelve long, slender leaves. The roots are fleshy and stay within the compost. They are variously called semi-terrestrial and semi-epiphytic. The flower spike arises from the base of the pseudobulb, within the axil of one of the lower leaves, and grows two to three feet tall (sometimes more). It appears in the fall, and the flowers open from December through April, depending on the habit of the particular plant.
