Paper white narcissus bulbs are pre-cooled and ready to be planted inside without any special treatment. Paper whites bloom in clusters of tiny, fragrant, daffodil-like flowers in either white or yellow. They are often planted in bowls or relatively shallow containers with just enough gravel or pebbles to hold them upright. They can be planted in deeper pots also. Just place the containers in a sunny area and keep them watered. They will bloom without any further treatment in about 4 to 6 weeks
Large or miniature amaryllis bulbs can be forced into bloom in large, 6 to 8 inch pots. Large amaryllis are generally planted one bulb per pot, and smaller miniatures 3 to a pot. This native South African flower has already been pre-treated and will bloom in 5 to 8 weeks after planting. If you have an amaryllis from last year, quit watering now and place it in a dark, cool place such as a closet for about 6 weeks. Then it can be brought into the light and will bloom again.
Tulips, daffodils, crocus, hyacinths and grape hyacinths are best for growing in pots with a cold treatment. The best tulips for forcing are the triumph strain which have medium height stems. Read labels or ask for the varieties which are best for indoor flowering. Almost any daffodil can be forced into bloom. Miniature narcissus or daffodils can also be grown in pots. Hyacinths are the most fragrant of bulbs. Single bulbs can be forced in a special hyacinth glass which has a lower chamber for roots and water and an upper one for the bulb. They can also be bloomed with several bulbs planted in a pot. It requires a 12 week treatment after planting in a cool dark place such as a refrigerator for bulbs to develop roots. Then they can be brought inside to bloom in about 3 to 4 weeks.
