Botanical Name: Narcissus jonquilla 

Paperwhite Narcissus is easy to force into bloom indoors. The bulbs do NOT need to be placed in cold storage to bloom. Paperwhite bulbs begin to grow as soon as they are planted, with fragrant flowers appearing in 4-6 weeks.

Each tall flower stem produces several small, snowy-white flowers. Make your flowers last longer by keeping the plant in a cool location. Blooms will look fresh for 3-4 weeks if kept at a maximum of 65°F/18°C.
 
Paperwhites are also sold as kits for the holidays. They're foolproof.
