Hydrangea is a shrub with flowers consisting of large, lush clusters of many blossoms. When they are fresh most of the flowers in the cluster open, the flower is sturdy and firm to the touch. They greatly benefit from proper hydration and will typically last 5 to 7 days longer. They come in many different shades of blue, purple, pink, white, green, and some deep burgundy.
