Let's Dance Sky View big leaf hydrangea (H. macrophylla) is a standout for consistent, yearly blooming, whether you grow it in cold or warm climates. You'll also love how easy this cultivar is to turn blue, which is what we recommend, since it’s so spectacular this way: flowers emerge a beautiful sky blue with a honeydew-green eye before maturing to a full sky blue. Its nice compact growing habit makes it both a good container and garden plant.
