Description
A new variety of hydrangea in the Japanese tradition. Masses of large, doubled florets are more refined than those of the more familiar mophead hydrangeas. Flowering begins in summer with pink or blue flowers (depending on soil pH). As the season progresses, bloom color deepens into shades of rich red. This variety is very floriferous and long blooming. ‘Shamrock’ is somewhat more compact than other hydrangea varieties, and may be slightly more frost resistant.
