The Cotton Rose Shrub is unlike most hardy Hibiscus which bloom in summer, Cotton Rose produces its large and beautiful flowers during the fall season. In our north-central gardens the flower buds start opening in October continuing all the way through late November to early December, depending on the weather. What's really neat is how the flowers change color after opening. They open pure white then gradually turning to darker shades of pink until ending up a deep rose-pink to nearly red. Because buds open at different times the result is all these different colors on the same plant at the same time. Truly a spectacular sight to behold! (USDA Zones 7-11)
