I purchased the tuff stuff hydrangea in April 2017. It had a couple of blooms when it arrived but after transplanting no additional blooms occurred for the remainder of the 2017 season. This year I have one bloom that occured in July 2018. Even with only one bloom this season it is beautiful. Overall it looks healthy and happy, I just wish for more blooms...hopefully next year. I live in zone 5a and it has survived two winters. For me it is not a fast grower but I did not expect it to be. Overall, I am happy with my purchase. I can't speak about it being a rebloomer because for me this has not yet occured.
