Helianthus hybrid

The F1 Helianthus hybrid (Jerusalem Artichoke X 'Red Sun' sunflower) is still flowering like crazy and mama is just now starting to form buds (second picture).The F1 hybrid has been flowering for two months now (since late June) and has topped out at about 7 feet tall. It's a giant flowering machine! Third picture is another side by side comparison - hybrid on the left, mama on the right.
