This amaryllis flower was given to us by Grandma --

It was the cooolest plant to watch grow... we literally could see it grow... 3 inches in a day, etc

We were fascinated!

I found this on the amaryllis.com website.  -

After-Bloom Care
After-Flowering. After the amaryllis has stopped flowering, it can be made to flower again. Cut the old flowers from the stem after flowering, and when the stem starts to sag, cut it back to the top of the bulb.
Leaf Growth and Development. Continue to water and fertilize as normal all summer, or for at least 5-6 months, allowing the leaves to fully develop and grow. When the leaves begin to yellow, which normally occurs in the early fall, cut the leaves back to about 2 inches from the top of the bulb and remove the bulb from the soil.
Bulb Storage. Clean the bulb and place it in a cool (40-50 deg. F), dark place such as the crisper of your refrigerator for a minimum of 6 weeks. Caution: Do not store amaryllis bulbs in a refrigerator that contains apples, this will sterilize the bulbs. Store the bulbs for a minimum of 6 weeks.
Plant Again. After 6 weeks you may remove bulbs whenever you would like to plant them. Plant bulbs 8 weeks before you would like them to bloom.
