Endless Summer is well-known for their collection of reliably beautiful, reblooming Hydrangeas, and the Bloomstruck Hydrangea is no exception! Dr. Michael Dirr of Plant Introductions, Inc. first bred this remarkable hydrangea, and gardens across the nation have never been the same since. The Bloomstruck Hydrangea has a neat mounding growth habit of dark green foliage that will reach 3-4′ across with a spread of 4-5′. Rose-pink, purple, or blue mop-head blooms grow 3.5 – 5 inches across. Like other Macrophylla Hydrangeas, you can change the color of your blooms by raising or lowering the pH level of your soil. More acidic soil will bring out the blue tones in the blooms, and more alkaline soils will produce pink blooms.
Although capable of several colors, the Bloomstruck is most noted for its rich violet-blue flowers which truly separate it from the pack. Enjoy the beautiful blooms all season long, as this landscape treasure continuously reblooms from spring to fall.
Additionally, the BloomStruck Hydrangea produces strong and beautiful red-purple stems that add a fantastic contrast to the dynamic, rich flowers. BloomStruck Endless Summer Hydrangeas are renowned for their ability to bloom on old and new wood!

Endless Summer Bloomstruck Hydrangea Care
Hardy from Zones 4-9.
Plant the Bloomstruck Hydrangea in partial shade in all zones. However, these Hydrangeas can handle some direct sun. Gardeners in the Northern US can allow around 3 hours of direct sun, while gardeners in the Southern US won’t want to allow more than 1-2 hrs of direct sunlight. Err on the side of caution as they are very susceptible to burning with too much direct sun exposure.
Hydrangeas need constant moisture to thrive, therefore supplemental watering may be necessary to ensure their success in times of drought. In addition, we recommend watering them a couple times per week while the plant is establishing itself. This will help it establish deep roots that are able to tap water from deep in the soil.
Standing water will cause root rot and the rapid demise of this plant. Consequently, well-draining soil is essential for the Bloomstruck Hydrangea.
We recommend fertilizing with a slow-release fertilizer in late spring or summer. Furthermore, fertilizers with a balanced NPK ratio will work, however, you may want to choose a fertilizer that is higher in Phosphorus. This will encourage increased bloom production.
