Emeralds are one of the most fascinating gemstones. Their radiant green color is not only unique as a precious stone, but also as a Hydrangea. Mystical® Emerald blooms in the spring with soft-pink flowers, each with a green eye. As the flowers mature they take on a soft-green color in keeping with the mild days of spring. Like all precious gems, Emerald continues to intensify. The soft-green flower heads take on their emerald-green color, retaining its lively vigor in all its nuances!
