Orchids are beautiful and fascinating plants. But the thought of growing orchids, especially indoors, is intimidating for lots of gardeners. It conjures up pictures of giant greenhouses, complicated humidity, light and heat controls, and horticulturalists in white lab coats. Despite their reputation for being finicky flower divas, orchids aren't difficult to grow.

Like any plant, they'll thrive in the right conditions. The trick is sizing up your indoor environment and choosing the orchids that will be happy there. Three of the best orchids for windowsill gardening are: Paphiopedilum, also called paphs; Cattleyas, catts for short; and Phalaenopsis or phals. Among them, you'll find colors, fragrances and sizes to fit any space.
