I have Echinacea 'Sundown,' 'Orange Meadowbrite,' 'Harvest Moon,' Tomato Soup, and 'Summer Sky' growing together. The 'Orange Meadowbrite is always the first then followed by 'Sundown.' It looks like the 'Harvest Moon' will be next. I also planted 'Tiki Torch' but it didn't make it. When the Orange coneflowers started hitting the market a few years ago, I was elated. I still love the pinks but there is something unusual about orange colored daisy like flowers. I may end up with every orange out there - If I can keep them alive!
