Blooms Each Year, Reliably

 

Why Endless Summer® Hydrangeas?

You'll have the look of summer, long after the season is over. Blooming early in the summer season, the incredibly beautiful, frost-proof Endless Summer® Hydrangea will give the warmth of summer to your garden with lovely blooms up until Thanksgiving.

Compare that to other typical varieties that only bloom for a few weeks before withering for the year. And the colorful blooms of the Endless Summer® are gigantic, offering a parade of flowers that thrive whether they're planted in shade or full sun. Hydrangeas make great hedges, too, so you can line a fence or walkway with them.

What is a Jumbo Endless Summer® The Original Reblooming Hydrangea?

Jumbo shrubs are the most mature shrubs offered at Fast Growing Trees. Thanks to their well-developed root systems and large container size, they provide excellent drought resistance and improved nutrient absorption. Jumbos are ideal for creating immediate privacy and adding fullness to your garden beds without the wait.

Grown in limited quantities, Jumbo shrubs are perfect for homeowners who want fast results and a lasting impression in their landscape.

Why Fast-Growing-Trees.com is Better

For starters, you get versatility. You can change the color of the flowers you produce simply by adjusting the pH in your soil. For blue, adjust the soil to have a higher acidity. And if hot pink is your preference, just go to more alkaline soil.

But the best part? We've planted, grown, and meticulously monitored this variety for best results at our nursery...now, you reap the rewards of our hard work with a healthier root system, more developed growth, and bigger blooms. You won't get the same experience from your local nursery or big box.

So if you can't get enough of your favorite season, the Endless Summer® Hydrangea is definitely for you. Order yours today!

No blooms but looks like

No blooms but looks like a healthy green bush.

Fast Growing Trees Plant ExpertHi there, Thank you so much for checking in with us! We are absolutely thrilled to hear that your Endless Summer Hydrangea is looking like a happy, healthy green bush in its new home. Please don't worry about the lack of blooms just yet. Since your hydrangea has only been in the ground for about two weeks, it is currently in its quiet, vital root-building phase. When a new shrub is transplanted during the summer, it smartly puts all its energy underground to anchor into your native soil. If it tried to push out massive flowers right now, it would actually tire itself out! Sometimes, even if we put extra care into watching it daily, Mother Nature prefers to build a strong foundation first. The great news is that you chose an Endless Summer variety! Because it blooms on both old and new wood, it doesn't just flower once in the spring. Once those roots finish settling in over the next few weeks, your healthy green bush will have plenty of strength to send up beautiful new blooms later this season.

Two days after I planted

Two days after I planted my hydrangea, we had a frost. It did affect the tips of the leaves but those tough plants survived. Now it is a thriving plant with beautiful blue flowers.

Fast Growing Trees Plant ExpertHi Jean, a frost two days after planting is quite the welcome to the garden! We're so glad your Endless Summer Hydrangea pushed through and is now rewarding you with gorgeous blue flowers. It's a tough and resilient variety and yours is proving exactly that. Thank you for sharing this!
