Paperwhite narcissus are related to the yellow daffodils of spring. They are native to the western Mediterranean, from Greece to Portugal, Morocco and Algeria. They grow from bulbs, forming grassy foliage and wonderfully fragrant flowers.
If you want to try growing paperweight narcissus bulbs, you could get a starter kit-- instructions, bulbs, soil and pot included--everything you need. These are very popular at holiday time, and you can find them at Walgreens. They make great gifts, and a fun project for kids, too.
In a few days, you will see signs of growth. You can move the container to a brighter location, and watch the roots, leaves and flower stalks forming. All the energy to produce this plant is stored in the bulbs. You are "forcing" them to bloom, by creating springlike conditions.
The flowers will last several weeks indoors. Keep them in a cooler place if you want the flowers to last longer. When the flowers are finished, most people toss the plants, as they are not easy to carry over once they have been forced into bloom.
