We've known a couple of orchid fanatics over the years -- people who keep entire greenhouses devoted to hundreds of them, and delight in the cross-breeding, all of that. It always seemed so extreme that we had no interest in the plants until a couple of years ago, when we received one as a gift and learned how easy their care can be.
We've only ever had the simple white or purple Phalaenopsis, which you can find at Smith & Hawken, starting at $29 -- or Trader Joe's, where prices start at about $8 for small ones. If you choose a plant with closed buds, and feed it a couple of pieces of ice once a week, it can last for up to three months.
And since orchids photosynthesize at night, producing more oxygen during that time, they're perfect for the bedroom, where they'll help enhance your sleep.
