Place the container in a cool place. Within days strong roots will appear. As they grow, they will sometimes push the bulbs upward. When the green shoots appear, move your project to a cool, sunny spot. The roots will develop rapidly and in about three more weeks, you'll have masses of heavily-scented sweet white flowers.
Amaryllis bulbs are very large but very easy to grow.
These big bulbs are normally planted one to a pot and are also available in complete pre-packaged kits. Begun six weeks in advance, amaryllis can be easily brought to flower for the holiday season. By starting a new pot every few weeks, it's possible to have amaryllis blooming in the house from December through April. Fill in with soil and gently pat down, leaving the neck and shoulders of the bulb exposed. Place in a cool sunny spot.
