flowers from my boys

I got flowers from my boys for Valentine's Day and forgot to snap a picture of them at the beginning of their long lives. Pro Flowers is definitely worth the money! These little guys came on Friday, the 12th, and the picture of them in the larger vase was taken on the 21st, I think.
Then I cut them down and put the best ones in my new IKEA vases two days ago.
They're getting a little wilty at this point, but only if you touch them and see that they're a bit floppy-headed. If you just look at them w/o touching, they still look great! If I'd gotten more than two packets of flower food, I'm convinced they'd have lasted longer. Can you buy that stuff at the store in a larger quantity than the little packets?
Thanks, boys, for my pretty flowers! I love you!
