My sunflowers were pretty successful this summer. I had about half a dozen plants, or stems, with several different color varieties. The original flowers didn't last long, a combination of yard critters and a couple of windy rainstorms pulled down those first large flowers. But I never cut down the plants afterwards, and now they are sending out tiny flowers up and down the stems. Each bloom is only about 2-3 inches across, they're somewhat mishapen, but are a nice surprise in my rapidly aging October flowergardens!
