While Snowflake hydrangea is the most popular selection of oakleaf hydrangea Eddie Aldridge introduced, Harmony hydrangea has it own special appeal. As you can see in the photo of a side by side comparison in my garden, Snowflake tends to be more upright flower spikes, while the weight of the Harmony flowers tend make most of the branches arch downward. The post,“Birmingham’s Best Native,” tells you about Snowflake, but I wanted to give you a few observations on Harmony. As you can see, the flowers are very dense on the flower spikes, and even when they are in the green bud stage, they are distinctive. As they fully open, the flower spike are–in a word–sensational. I have cut them many times for indoor use. The other thing is that my Harmony hydrangea is about 3/4 the size of the Snowflake. The only downside I see to Harmony is if we have a prolonged wet period, the flowers will tend to rot, as the spikes are so dense.
