Hydrangea in November…still blooming!

Um….is this normal? It was such a beautiful day doing chores in the late November sun was a delight, though it was clear as a bell it was also very chilly. It struck me as amazing to see white, pink, and blue/purple blossoms on my large hydrangea. . . and in the middle of November no less! I can see some of the leaves are turning now but the blossoms keep on going!
