Why do flower petals die and fall off but the stems seem fine?
My step-father got my mom flowers for Valentine's day, except now the flower petals are starting to fall off and die, but the stem seems perfectly fine, why is that?

Basically, it is because there are very strong cellulose fibers in the stem, but not in the petals. Those stems can last for hundreds of years because of those fibers.

Pink Flower, Oxalis Weed Macro
If you remember seeing either of my two images from almost a year ago of yellow oxalis flower macros here and then here, you can imagine my surprise to find some large oxalis weeds volunteering in my rock garden. And I've found that one of them is producing tiny pink blossoms! This one will look best large, and I'm going online to find out more about this variation. I wonder why the weeds that volunteered last year in this same place gave double, ruffled yellow blooms and now this same area shows up with the pink blooms. Obviously there are three distinct varieties of this wildflower growing in my urban yard. Ah, mysteries.
Best ID's I've found so far:
sid.fcla.edu/mrsid/bin/show.pl
(This one, above, is an amazing size with a scanned huge image of a pressed plant. It's worth looking at to see the method the University of Floriday uses to display these for identification.)
Their info is:
Oxalis debilis
pink wood sorrel
And listed as an Invasive Plant:
"Pink wood sorrel is an escaped exotic ornamental plant that is now found throughout Florida (Wunderlin, 1998). It is native to tropical America. Pink wood sorrel flowers from spring through fall. There are about 30 species of Oxalis in the U.S., with 6 in Florida. A number of them are not native to the U.S. (Kartesz, 1999)."
