A common trait among the panicle hydrangeas is the ability of the flowers to change color, and in the case of 'Strawberry Shake,' its flower heads emerge white, gradually deepening to pink. Standing at four to five feet tall and wide, this variety is considered compact in size, making it a wonderful option for back-of-border, large container planters, or as a foundation plant. The other trait that so many gardeners love about panicle hydrangeas is the ability to grow in sunny locations and in fact, bloom more profusely with more sun. Flowers appear on new wood, so be sure to cut back panicle hydrangeas in the fall when dormant or late winter, before new growth begins.
