- Grow paperwhites indoors in a shallow pot or bowl (3-4 inches deep) without drainage holes.
- Fill the pot with small, loose stones.
- Gently place upright paperwhite bulbs into the container, pressing them into the stones.
- Add just enough water to cover the bottom of the bulbs.
- Store bulbs in a cool, dark room for 4-6 weeks. Move to a cool, sunny place when shoots begin to sprout.
- For shorter, more stable stems, grow paperwhite bulbs in water with a 5% alcohol concentration.
- Paperwhite bulbs can also be planted outside in the fall in warm climates.
- Wouldn't some bright, fragrant blossoms perk up your house this winter? The paperwhite narcissus, a relative of daffodils and jonquils, is easy to grow indoors and produces small, fragrant flowers on 12- to 18-inch stalks. Most paperwhites display pure white blooms, but yellow and orange varieties are also available.
How to Plant Paperwhites Indoors
The most common way to grow paperwhites is to grow them to bloom in pots indoors. They are especially popular for decorating at Christmastime. Fill a 3-4 inch deep bowl or other shallow container without drainage holes with crushed rock, pebbles, or other decorative stones. Pack your paperwhite bulbs into the container and push them down into the stones so the tips stay upright. Add water until it just covers the bottom of the bulbs.
How to Force Paperwhites to Bloom
After planting, keep the bulbs in a cool, 65 degree, dark room for several weeks until the roots take hold and shoots start to sprout from the bulbs. Then place the containers in a cool, sunny location. In 4-6 weeks, you'll see tiny blossoms on the flower stems. Paperwhites have a significant advantage over other commonly forced bulbs in that they do not need an 8- to 12-week cold-temperature treatment. ("Force" means to coax a plant to bloom out of season.) Because it's so fast and easy, forcing paperwhites is an excellent project for beginning gardeners.
Plant Outdoors in Warm Climates
Unlike their daffodil relatives, paperwhites won't tolerate freezing temperatures, but they can be planted outdoors where winters are mild. Plant them in the fall as you would other spring-flowering bulbs. They look especially attractive in groups planted in containers or the garden.
A Tip for Growing Paperwhites Indoors
To prevent your paperwhites from getting tall and floppy, give them a good, stiff drink. Paperwhite bulbs grown in water with a 5% concentration of alcohol bloom beautifully on stems 1/3 shorter than paperwhites grown in unspiked water. Most clear liquors are about 40% alcohol (80 proof), so that works out to 1 part liquor to 7 parts water.
