For the past 15 years, since I moved into this house, I get a couple of indoor blooming amaryllis each year for Christmas. And every year, after they've bloomed and the weather warms up some, I plant them in an island bed in my front yard. I've even gone so far as to mail order a few bulbs of the more exotic types that you don't see in stores.
Now, I have a bed full of amaryllis! It's a wonderful sight to see them in bloom. Depending on the variety, they bloom from springtime to early fall. And they've multiplied like crazy! This year, I really need to rework that entire bed, dividing the bulbs.
