My photo is a picture of two Tuscan Suns. A great plant for me as it sails through winter wet and so far has been mildew free. Tuscan sun is a strong golden yellow about 3'x3' in my yard. Started blooming in beginning of June. It's July 17th and I've yet to find a faded bloom to deadhead. It's in its second year in my garden in fairly moist soil with about 6 hours of direct sun. I'll update when the bloom has ended.

Late to update. The flowers on all of my heliopsis plants were found to contain larvae from the sunflower moth, but of more importance to me, they were susceptible to the same bacterial disease that affects many asters. I have since removed all aster and heliopsis plants that show signs of this disease. I do not use chemicals, so sometimes removal is the only option.
