It’s hard not to be fascinated by orchids. They have, after all, conquered every continent on earth except for the Arctic and Antarctic. In your home and garden, these long-living flowering plants will add instant style and grace. Orchids can be grown indoors or outdoors and, as a native of tropical east Asia, some varieties will even thrive in your warm, steamy bathroom. Orchids also make excellent gifts, if you can bear to part with them.
