Strawberry Sundae HydrangeaAnother great "First Editions" plant introduction, 'Strawberry Sundae' is a delicious new compact SUN hydrangea with flowers that emerge creamy white in mid summer, change to pink as nighttime temperatures drop and finally to strawberry red in fall! Because Hydrangea paniculata blooms on new growth, they'll bloom even when late freezes kill back stems. If you prune, do so in late winter to early spring.
