An absolute breakthrough for this much-desired species, this spectacular summer-bloomer is not only very hardy, but it blooms on both old and new wood; enormous deep pink globe-shaped flowers turn blue in acidic soil, somewhat coarse leaves
Endless Summer Hydrangea features bold balls of hot pink flowers with blue overtones at the ends of the branches from early summer to early fall. The flowers are excellent for cutting. It has forest green foliage throughout the season. The glossy pointy leaves do not develop any appreciable fall color. The fruit is not ornamentally significant.
Endless Summer 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.
Endless Summer Hydrangea is recommended for the following landscape applications;
- Mass Planting
- General Garden Use
- Container Planting
Planting & Growing
Endless Summer Hydrangea will grow to be about 4 feet tall at maturity, with a spread of 4 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 does best in full sun to partial shade. 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.
Endless Summer 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.
