What the Experts Are Saying
Awarded the Green Thumb Professional Award by the National Garden Bureau and the Retailer’s Choice Award at Cultivate 2025.
“The ruby red mophead blooms of this new bigleaf hydrangea are real showstoppers! They start in late spring and keep going until early fall. The color deepens as the bloom ages so you have different shades of red on one plant”
—Garden Gate Magazine, Best New Shrubs for 2026
