    Landscape Attributes

    Bloomstruck® Hydrangea is a multi-stemmed deciduous shrub with a more or less rounded form. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage.

    This shrub will require occasional maintenance and upkeep, and should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.

    Bloomstruck® Hydrangea is recommended for the following landscape applications;

    • Accent
    • Mass Planting
    • Hedges/Screening
    • General Garden Use
    • Container Planting

    Planting & Growing

    Bloomstruck® Hydrangea will grow to be about 4 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.

    This shrub should be grown in a location that is shaded from the hot afternoon sun. It requires an evenly moist well-drained soil for optimal growth. It is not particular as to soil type, but has a definite preference for acidic soils. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.

    Bloomstruck® Hydrangea makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.

    At Dutch Growers, we treat this plant as a "HOBBY PLANT". It is not officially recognized as winter-hardy in our zone 3, however, there is a strong liklihood that it will survive winter. Warranty expires on Nov. 1 season of purchase.
