hydrangea flowering in 5a
Hi, I went to my friend yesterday to pick up some tools. Anyways, I saw about 6 hydrangeas outside against the unheated garage. I saw the dried spent flowers. I asked him what color the flowers were. He told me that it was color blue. Next, I asked him how old it is. It was 3 years old. Last question I asked him what about the flowering. He said, that it never missed any flowering.
The hydrangeas were planted in the east wall.
This friend of mine doesn't care about plants much at all. He is about 10 miles north of me. So what could be the reason why it still blooms? I read on our Hydra FAQ that in zone 5a, the plant will live but won't flower.
