I guess I sound like a broken record with this one, but sheez it just won't stop blooming!
It's mama was Jerusalem artichoke (a perennial tuberous sunflower used as a vegetable); it's papa was the annual 'Red Sun' sunflower. I was hoping for red-flowered (or eye-zoned) perennial but instead I got this very long blooming perennial hybrid. It started in late June and hasn't been without blooms ever since. Two months plus! In the first picture, it's on the left and the mama is on the right (still working on making buds - no open flower yet).
