Hollyhock “The Watchman”
My hollyhock plants have not produced any stalks or flowers this summer (new plants from local garden center). Any suggestions on what is wrong?

Holly Hocks are thought of as a perennial, but they really are a Biennial.
You may only see blooms every other year.
With that said, you may also have to much Nitrogen in the soil for flower production.
You can add Phosphorous to the soil which will encourage blooming. Bone Meal is good way to do this.
Here are a few links for you.
