Description

‘Glory Blue’ is a vigorous growing mophead Hydrangea that produces LOADS of large and “glorious” spherical clusters of deep blue to pink flowers summer, depending on soil pH. Acid soil makes blue floowers and alkaline soil makes pink flowers. The prolific blooms appear on rounded, bushy plants that grow to about 4 feet tall and wide. This is a great cultivar for garden beds or container culture.

It provides great texture and color as an accent in home foundation plantings and in flowering shrub borders and perennial gardens. It is especially stunning in small to large groupings or as a dramatic, colorful hedge.

Growing Preferences

Glory Blue Hydrangea are easy to grow in average, moist, well-drained soil. The plants will tolerate full sun in northern zones however will appreciate some afternoon shade or filtered sun in warmer southern zones. We recommend at least 5 hours of direct sunlight per day or all day lightly filtered sun for best flowering. Mophead-type Hydrangea produce blooms only on old wood (growth from the previous year). This means that even though it is tempting to cut them back in the winter, when they are only bare sticks jutting out of the ground, don’t do it. The flower buds are already formed and hidden in those bare sticks, so don’t cut them off if you want flowers! Click here for expert Hydrangea pruning tips. USDA Zones: 6a-9b Find Your Zone
