Additional Information

'Bailmer' is an excellent mophead (hortensia) cultivar for cold climates, as it is hardy to USDA zone 4 and produces flowers on both old and new growth, unlike other Hydrangea macrophylla variants. As the name Endless Summer suggests, this plant blooms all summer, and even into the fall. An acidic soil will produce a very blue colored flower and alkaline pink. High quality foliage. Performs poorly on hot dry sites. A few pest problems, including scale, mites, powdery mildew, and leaf spot.
