Hydrangea in the Japanese tradition with masses of large, doubled, pink lace-cap flowers. Flowering begins in July and as the season progresses they transform into breathtaking shades of red and deep pink. On acid soils the flowers are more violet. Very floriferous and long blooming. More compact and tends to be more frost resistant than most Japanese types. Developed by the world famous French hydrangea expert Corinne Mallet. This superb new plant pays tribute to Association des amis de la Collections D'Hydrangea Shamrock (French Hydrangea Society) and a portion of the royalties are used to support their Hydrangea collection near Dieppe in Upper Normandy. Zone 4, 3.5-5 feet, gr 1, full sun - partial shade
