Mountain hydrangeas bloom on both old and new wood, and their growth depends on the type of hydrangea. They bloom later in the season, on the growth that’s created in the previous season. Old wood hydrangeas are stiffer, tougher, thicker, and more grey or brown, while new wood hydrangea stems grow in the present season and from the base of the plant.
