Arranged along stems like so many exotic butterflies, Phalaenopsis flowers look almost too perfect to be real. But if you've never grown orchids before, you may wonder: Can you grow these hothouse beauties without a greenhouse? And can you get them to rebloom easily?

Happily, the answer to both questions is yes. Moth orchids can bloom year after year in pots on windowsills; household temperatures suit them fine. Flowers come in white, pink, and other colors. Some have spots, stripes, or weblike patterns; all are gorgeous.

Moth orchids are sold in 4-inch pots for $15 to $75 each. Choose a plant with at least two pairs of leaves whose flowers are just starting to open. Display in bright, indirect light (an east window is usually perfect) out of drafts.
