Paper white narcissus do not need cold treating so I started a bagful of those earlier this month to be ready by Christmas. They were cheap at Home Depot and I have several containers going. One trick I learned on this site last year: after the stalks are 5-6 inches tall, drain and change out water with vodka/water solution (7 parts water, 1 part alcohol if using 80 proof cheap vodka). Water with alcohol/water solution and stalks will be markedly shorter, no flopping over, and blooms are just as nice. Started a tradition last year of growing a jar full of these for a friend, delivering them to her office when they are almost blooming.
For other bulbs that do need cold treating jmorth's directions are great.
