Oh, that's how it works....

I had an agave that flowered after six or seven years.  I think it may have been a coyote agave, but really, I can't remember.  Most all of my many agaves have been attacked and killed by "el toro," a beetle that attacks the roots and is one tough insect.  However, this agave survived long enough to flower and when it was done, I pulled the plant and cut the flower stalk to let it dry.  

Weeks later, these little plants appeared on the fertilized flowers.  I've never had a stalk around long enough to see this happen before and I guess I have babies to cultivate.
