The hybrid hydrangea was developed by two University of Georgia horticulturists, Michael Deere and Tom Raney, who hybridized two different hydrangea species – macrophylla and serrata – to create a plant that blooms repeatedly throughout the summer months, making it a unique and versatile plant.

The Endless Summer Hydrangea has several distinct characteristics that make it stand out from other hydrangea varieties:

Care Tips for the Endless Summer Hydrangea:

Endless summer hydrangeas are relatively easy to care for and with proper care, they can produce beautiful flowers year after year. Here are some tips for caring for your endless summer hydrangeas.


The Endless Summer Hydrangea prefers partial shade, especially during the hottest part of the day. However, it can tolerate full sun in cooler climates.


The Endless Summer Hydrangea prefers moist, well-draining soil that’s rich in organic matter. You can amend the soil with compost or peat moss to improve its texture and fertility.


Endless Summer hydrangeas require consistent moisture to thrive. Be sure to water regularly, especially during periods of drought or hot weather. When watering, aim to keep the soil consistently moist but not waterlogged, as this can lead to root rot and other fungal diseases. Mulching around the base of the plant can help retain moisture in the soil and regulate soil temperature.


Fertilizing your Endless Summer hydrangeas is crucial to ensure optimal growth and bloom production. We recommend using Holly-tone for blue flowers or Plant-tone and granulated lime for purple to pink flowers. For best flowering, fertilize in April, May, and June with 1 cup of fertilizer for each foot of branch spread. For example, a 3 foot wide plant would receive 9 cups of fertilizer over a 3 month period. Avoid fertilizing after this period, as it can cause excessive growth and reduce the number of blooms.


Endless summer hydrangeas should be pruned in late winter or early spring, before new growth begins. Remove any dead or damaged wood and cut back any old wood to encourage new growth. Be careful not to prune any buds, as this will reduce the number of flowers.

When to Prune Endless Summer Hydrangea:

The best time to prune your Endless Summer Hydrangea is in late winter or early spring, before new growth begins. This is because Endless Summer Hydrangeas bloom on both old and new wood. If you wait too long to prune, you risk removing new growth that will produce blooms in the upcoming season.


How to Prune Endless Summer Hydrangea:

When pruning your Endless Summer Hydrangea, start by removing any dead or damaged wood. Next, prune any stems that are crossing or rubbing against each other. This will help the plant grow evenly and avoid any potential disease or pest issues.

For Endless Summer Hydrangeas, it’s also important to remove any spent blooms. This will encourage the plant to produce new growth and more beautiful blooms. To do this, simply cut the stem just above the first set of leaves below the spent bloom.

If your Endless Summer Hydrangea is getting too large, you can also prune it back for size control. However, it’s important to keep in mind that pruning too much can lead to a reduction in blooms. Only prune back up to one-third of the plant’s total height to avoid this issue.

Tips for Pruning Endless Summer Hydrangea:

When pruning your Endless Summer Hydrangea, be sure to use sharp, clean tools to avoid damaging the plant. You can also use pruning paint or paste to seal any cuts and protect the plant from disease or pests.

In addition, it’s important to water your Endless Summer Hydrangea regularly, especially during dry spells. This will help the plant produce healthy growth and beautiful blooms.

Propagating Endless Summer Hydrangeas:

Endless summer hydrangeas can be propagated in a number of ways, including by stem cutting, layering and division.

Stem cutting:

To propagate perennial summer hydrangeas by stem cutting, select a healthy, non-flowering stem and cut a 6- to 8-inch section just below a node. Remove the leaves from the lower half of the stem and dip the cut end in rooting hormone. Plant the cutting in a pot filled with a mixture of peat moss and perlite and keep the soil moist until the cutting roots.


This involves bending a low-hanging trunk of a plant into the ground and burying a portion of it underground. Once the stem has developed roots, it can be cut from the parent plant and transplanted.


This involves dividing the plant into smaller pieces by carefully digging up the root ball and splitting it with a sharp knife. Each section should have a healthy number of roots and shoots and can be transplanted to a new location.
