Hydrangea macrophylla 'P11HM-11' Bloomstruck

USDA Plant Hardiness Zones: 4a-9b  Find Your Zone

Special Attributes

'Bloomstruck' is a cross between 'The Original' and 'Twist-n-Shout', two members of the Endless Summer® series, Hydrangeas that were bred for their cold hardiness and the ability to bloom on both old and new wood. Bloomstruck produces an abundance of  4 to 5 inch wide mophead-type flower heads that are vivid deep rose to purple depending on the soil pH. The shrub will rebloom all summer long. It has strong red-purple stems and dark green leaves with red petioles and red veins and turns reddish purple in fall.

Landscape & Garden Uses

Growing to 4 feet tall and wide and producing abundant flowers throughout the season, the Bloomstruck Hydrangea is useful as an accent, in small groupings or as a natural hedge in home foundation plantings and landscape borders. It is also highly suitable for container culture and is ideal for use in cottage and cut flower gardens as well as purple color theme gardens.

Spacing:  3.5' for solid hedges; 7' or more for space between plants

Cultural Preferences

Bloomstruck Endless Summer® Hydrangea are easy to grow in average, moist, well-drained soil. An acid soil will create deep violet-blue to purple flowers while an alkaline soil creates deep rose-pink flowers. 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. Unlike other mophead hydrangea, you can prune the Endless Summer hydrangeas at any time of year, though we recommend a late winter pruning and a deadheading (removal of faded flowers) after its first flush of blooms have faded.

Note:  Bloomstruck is an everblooming Hydrangea macrophylla species that produces its flowers from buds formed on both new and old wood.
