So far this is my tallest sunflower at 10'2" on 7/25. It has a very small flower bud; so it should have a while to go before flowering. Last year I crossed a white shelled Norm Craven sunflower with a Bott's Strain sunflower, and this is the result. This cross, so far, has produced the best plants. Give me a couple years and I hope to make this into a stable variety.
