Hi, and thanks for using Ask Extension.
I am curious to know more about what you are seeing. When did you first notice it? Is it a one-time thing, or has it occurred over and over after any additional plantings? Did it happen overnight? Is the damage occurring just on annual flowers? Have you seen anything on the leaf or perhaps on the underside of the leaves or around the plants? Anything else unusual? Do you live where there are many animals? Has this happened before?
I feel your frustration - I really do. It is painful to spend the money and the time only to have it wiped out so fast. I have battled this myself in my garden in the country.
Simply due to the widespread and non-fussy eating habits, an unwanted animal pest is my first thought. People associate groundhogs with country life, but they are around in suburban areas too, and they are notorious for eating almost everything in sight. It's been my personal experience that deer and rabbits, while potentially destructive, can be slightly more discerning as to what they eat, but groundhogs will eat everything they can get their hands (paws) on.
Of course, like everything in gardening, you may have a couple of things going on, but I really do suspect groundhogs on this one. Here are a couple of links that might help:

The following comes from a fact sheet from the University of Connecticut: "Woodchucks are voracious feeders. In the early morning and evening periods of the summer, woodchucks actively feed on succulent, green vegetation. They are storing body fat in preparation for hibernation during late fall, usually near the end of October or early November.
Woodchucks feed primarily on vegetables, trees, grasses and legumes. Their favorite foods include various beans, cole crops (broccoli, cabbage, cauliflower etc.), carrot tops, clover, squash and peas. "

I hope this helps and I wish you luck!
