Thanks for the link, David.

Bulbs in the Amaryllis Family also contain physiologically active (i.e., 
toxic) alkaloids that serve as deterrents to animal predation.  So I wonder 
why Doug's daffodils in the mountains keep disappearing?  The only predator 
that occurs to me is bulb flies, which are not deterred by alkaloids.
