They are incredible, aren't they? My biggest problem was paring the pictures down!! Within flickr.com, there are countless others of pure perfection.
In the U.S., "Columbine" has come to signify the on-campus incident. (http://en.wikipedia.org/wiki/Columbine_High_School_massacre). It seemed the sad, sagging flowers were prescient -- they
knew their name would "become a byword". I looked up the meaning of the flower to tie it into that tragedy.
I was surprised that the Columbine is a buttercup, which I always associated with innocent childhood. When I thought of Columbine-the-flower before, I imagined the droopy-necked tightly draped
flower-head -- had no CLUE those perky multi-colored show-offs saying
"Ta-DAA!" were the same flower, fully opened. That tempered the poem, which I'd already predetermined would be just four lines.
(sigh) More than you want to know... are you backing up?
