Overview
  • Skill Level: Beginner

Forcing paperwhite narcissus to bloom couldn't be easier. After planting, they will bloom in four to six weeks. Paperwhites grow so fast you can almost see them sprout, which makes it a particularly great project to do with kids. If you start them about four weeks before Christmas, a fully blooming pot of paperwhites can make an easy and economical holiday gift. You can also give people the bulbs in a pot, coffee can, glass dish, or mug so they can see them grow.

To have continual fragrant blooms throughout the winter months, plant narcissus bulbs every couple of weeks throughout fall and winter. You can either buy your bulbs at a local nursery or get them online at Brent and Becky's Bulbs or White Flower Farm.

How to Stabilize Paperwhite Narcissus

Consider growing paperwhite narcissus in a tall jar or vase. It looks pretty and you don't have to worry about the weight of the flowers tipping the bulbs over. You can often find inexpensive vases in craft or thrift stores.


Try using smooth stones, which you can buy in a nursery or craft store, but you can use anything that isn't absorbent for this project.

  1. Add 2 to 4 Inches of Stones

    Fill the bottom of your glass jar, vase, or bowl with about 2 to 4 inches of stones, marbles, or sea glass. The purpose of this to give your bulbs stability and to keep the bulbs to above the water while allowing the roots to stay wet. If the bulbs sit in water, they tend to rot.

  2. Place Your Paperwhite Narcissus Bulbs

    Place your bulbs close together on top of the stones. Nestle them into the stones until they are stable. It's very important to make sure all the bulbs are sitting at the same level so that the roots, not the bulbs, will be sitting in water.

  3. Add Water to Your Bulbs

    Add just enough water, so the level is below the paperwhite narcissus bulbs but is wetting the roots, which at this point are usually just dry strings. This is very important because if you leave the bulbs sitting in water, they will rot.

Growing Tips for Long-Lasting Paperwhite Flowers

For optimal growing, keep your bulbs in a cool spot (50 to 60 degrees Fahrenheit), out of direct sunlight, for a couple of weeks until the roots have grown. At this point, they will be white.

After this rooting period, you must put them in a bright, warm spot. Some people recommend putting them under “grow lights,” or fluorescent lights. Or, if you want to speed up the flowering, you can also use a heat mat or heating pad underneath your bulbs.

That said, you could always place them somewhere like a kitchen counter that is bright but gets no direct sun. With regular watering, but without any extra attention, they'll do fine.

Paperwhites tend to fall over after they flower. This is more of a problem if they are in a shorter container. To prop them up, use some chopsticks or bamboo stakes stuck down the sides of the vase or bowl and encircled with twine or decorative ribbon.

After the blooms have faded, you can compost the bulbs.
