My mammoth ones are not super tall this year either, I also plant the autumn mix sunflowers and they are at least 6 ftI’m seeing monarch caterpillars on a local page now so we are at that stage here.
Some of my sunflowers are blooming but none are as tall as they were supposed to be. The “Mammoth Russian” are maybe 3’ tall with smaller heads. The ones that should have been about 4’ are half that too. My cosmos are actually taller.
