Dormancy Notice: This plant, like many others, enters dormancy or semi-dormancy in the late fall through early spring. *THIS PLANT IS NOT DEAD. It is completely healthy but upon receiving the plant, you may notice it exhibits fewer leaves, discoloration, or complete leaf drop. This is normal and essential to the plant's health. In fact, planting during dormancy promotes root growth, giving your plant a better start for spring, when new foliage will begin to grow.

Endless Summer Bloomstruck Hydrangea Shrubs for Sale Online

The Endless Summer® Bloomstruck Hydrangea (Hydrangea macrophylla) is a lovely shrub loved for its large multicolor blooms that make a bold splash in any summer garden. 

Reblooming every July and August, the Endless Summer shrub produces gorgeous mounds of flower heads that vary from violet-blue to rose, depending on the soil. Blooming on both old and new wood, these stunning blossoms are held up by strong red stems, a welcome contrast to the accenting green foliage. After the flowers fall in the autumn, these green leaves darken to burgundy to match their stems.

Since the soil pH determines the color of your Hydrangea blooms, here are a few tricks to achieve your desired hue. Add aluminum sulfate to make the soil more acidic for blue to purple blooms. Deep Rose flowers require a slightly higher pH, so we recommend you add lime to the surrounding soil to accomplish such. Plant in early spring for best results!

Like most hydrangeas, this bigleaf shrub enjoys moist, well-draining soil and can tolerate full sun but prefers part shade conditions. Praised for their impressive heat tolerance and resistance to powdery mildew, your Bloomstruck Hydrangea will indeed have you amazed by its hardiness.

The highly durable summer flowering shrub is popular in garden hedges, yard focal points, and garden borders. The plant's dark green foliage, paired with the variety of rose pink and blue blooms, will make your yard pop all summer. As a bonus, Hydrangea makes for stunning cut flower arrangements to bring your yard's outdoor beauty in.

How to Care for Endless Summer® BloomStruck® Hydrangea

Be sure to read our planting instructions to ensure a healthy and happy plant for years to come!

How should I plant my Endless Summer Hydrangea?

How should I plant my Endless Summer Hydrangea?

Plant your Bloom Struck Hydrangea in a hole that is twice as wide as the root system, but no deeper. Cover with well-draining soil and give your plant a good watering. These resilient plants can survive in clay or sandy soil, given that they receive plenty of water. To get a head start on these beautiful plants, opt for the 3-gallon pot for your garden. For gardeners in zone 5, plant your hydrangea where it can be sheltered and protected during the winter months.

How should I water my Bloomstruck Hydrangea shrubs?

How should I water my Bloomstruck Hydrangea shrubs?

As mentioned, Endless Summer Hydrangeas love moist soil so be sure to water your shrub at least weekly to maintain this. During the first season, it is best to water it more often in order to support an extensive root system that will encourage the hydrangea’s well being.

How do I fertilize an Endless Summer Bloom Struck Hydrangea shrub?

How do I fertilize an Endless Summer Bloom Struck Hydrangea shrub?

To encourage blooms, use a fertilizer that is high in phosphorus such as Jack’s Classic Blossom Booster. An organic alternative would be as compost or manure. Homemade compost is easy to make and fantastic at giving your plants the nutrients it needs.

What type of mulch should I use for my Bloomstruck Hydrangea?

What type of mulch should I use for my Bloomstruck Hydrangea?

Before winter begins, it is important to protect the roots from the harsh climate. I propose an organic material such as straw or mulched leaves for preservation. When spring comes, surround your hydrangea with ground hardwood or cypress hardwood mulch to retain moisture. Be sure to leave a small gap between the stem and the mulch to prevent rot.
