About two weeks ago, we were given some cut flowers, beautiful!  Carnations, 
daises, and lilies.  When I trimmed the stems to put them in water, the CS 
was sitting right there.  So I put about a cup into the water (rather large 
vase).  They are as fresh today as the day we got them.  I did change the 
water today, (starting to get an odor), and put in more fresh water and CS.  
We have never had flowers last that long, and it has to be the CS!
