Hydrangea Endless Summer® Description

Enjoy blue or pink blooms on this garden classic!

A favorite garden hydrangea for many years, Endless Summer hydrangea (Hydrangea macrophylla was selected in Minnesota by Bailey Nursery. It was found to bloom not just on old wood but also on new wood, which means a longer bloom time for warm climate gardeners and a better chance at seeing flowers for those in cold areas.

Giant 8-10" mopheads of a rich blue or pink (depending on your soil ph) begin in summer and continue well into fall.  Blooms on both old and new growth so if old growth is damaged by late spring frosts, flowers may still form during the summer on new growth. Glossy, leathery, dark green foliage.

How to grow Endless Summer hydrangea

Give copious amount of water during the prolonged summer dry spells.  This types has the ability to change flower color depending on the ph of the soil.  Produces bluest flowers in acid soils with a pH of 5.0-5.5, pink flowers in more alkaline soils with a pH over 6.0.

Soil: Average, medium moisture, well-drained soils. Mulch to conserve moisture, and buffer soil temperatures.
Generally, a soil pH below 5.0 results in deep, vivid blues, and as the pH rises, the flowers range from blue to lavender to mauve to a vivid deep pink at pH 7.0 (neutral). The pH determines the availability of aluminum in the soil; this element is more readily available in acid soils, and this availability results in the blue flower color. Since phosphorus ties up aluminum in soils, using a fertilizer low in this nutrient will aid in attaining blue flowers. If pink flowers are desired and your soil is acid, simply add lime to raise the pH and use a balanced fertilizer. Aluminum sulfate will lower pH if blue flowers are desired.
Light: Most varieties tolerate full sun in the north, but benefit from afternoon shade. Tolerates full sun only if grown with consistent moisture. In the south, plants require afternoon shade. Intolerant of drought, with foliage tending to decline considerably in dry conditions
Water: Water to keep soil moist, but not wet.
Spacing: 3-4 ft.
Fertilizing: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15).
Winterizing: Remove and destroy any fallen foliage that was infected by powdery mildew.
Maintenance & pruning: This variety blooms on both old and new wood. Cut back stems by August by about half if plants are growing too tall. Remove some of the oldest stems at ground level to thin out the shrub as needed. In spring, only prune out dead wood once the new growth has emerged. Young plants may be transplanted when dormant in early spring.
