If you haven't done paperwhites before, they're SUPER-easy. Hardware stores, grocery stores, garden stores and Amazon all carry the bulbs, for about $5 - $15 (depending mostly on how many you get). Put them in a pot or a glass dish with pebbles. (Maybe another $10-$15 to buy those?) Add water to reach the bottom of the bulb (if you cover the bulb with water, it'll rot). Put it in a sunny spot and leave it alone. Check on the water level every few days, and top it up if needed, but odds are, it'll be fine -- the roots will grow down into the water. In 3-4 weeks, flowers!
