I'm not one of those people who is at Target the day after a holiday to scavenge the newly-discounted post-holiday goodies. I do swing by the sale shelves occasionally, though, and picked up an Amaryllis bulb in its own pot sometime after Christmas for around $5.
The interesting stuff:cost ratio on this purchase has been really high. It doesn't exactly grow in front of your eyes, but almost. It's provided us with a couple of months of observation, and is now on its way out. I have researched how to make it all happen again, and am going to try to get this thing to rebloom next year. It involves lots of sun, then getting it outside, so I'm going to have to repot it into something that has a water reservoir because I'm not that good at remembering to water pots daily.
I have another Amaryllis that is at least 3 years old (post bloom, probably got that on sale, too) that consists of two leaves that limps along in a darkish corner of my living room and yearns to bloom again, so I'll bring it along for the experiment.
Mr W was suitable impressed with the growth of the bulb, and asked questions about what was going to happen, which I could reply with, "This, but wait and see, too". Totally worth the $5.
