Strawberry Shake Hydrangea
Hydrangea paniculata ‘SMHPCW’ PP #28,699

The cooler evening temperatures of fall bring out the magic in Strawberry Shake Hydrangea. The bright white, cone-shaped blooms begin to take on a delicate pink shade and mature to a deeper strawberry hue. This color transition adds even more interest to the late season garden. This panicle hydrangea, grown only by Monrovia, stays more compact, reaching only 4- to 5 feet tall and 4 feet wide, making it a great choice for adding color to small space gardens. It is spectacular in large containers or as a feature plant in the landscape. Recommended for Zones 4-8.
