August 4, 2021 | PLANT SPOTLIGHT
Panicle Hydrangea ‘Rensun’ STRAWBERRY SUNDAE™ (Hydrangea paniculata) is a popular hybrid deciduous shrub. It typically grows 4 to 5 feet tall and 3 to 4 feet wide. The flower panicles start white and age to pink. This Hydrangea is appropriate for USDA zones 4 to 8. A newer Hydrangea cultivar with consistently compact form and prolific blooms.
Scientific Name: Hydrangea translates to “water vessel,” referring to the typical shape of fruits in this genus. The species name paniculata references the individual flowers being arranged in panicles (branched clusters).
Flowers: Large cone-shaped panicles emerge on new wood. They start out white and age to a dark pink or strawberry red starting from the base of the panicle and moving upward, resulting in a flower that appears to be pink frosted with white for a time.
Fruits: Due to the flowers being sterile, this plant does not bear fruit.
Fall Foliage: Yellow – fall color is not considered a major feature of this plant.
Problems: No serious insect or disease problems. Some possible pests and diseases may include mildew, bud blight, bacterial wilt, leaf spot, and blister rust.
Landscape Uses: Used as a medium-sized flowering shrub for full sun to part shade. Adds late summer interest as it flowers at that time. As a smaller panicle hydrangea, it is also used in containers. Makes an excellent addition to the mixed border or when planted in masses/drifts in the landscape.
Location in Pittsburgh Botanic Garden: A grouping can be found along the western edge of the Weisbrod Learning Pavilion at the north end of the Garden of the Five Senses.
