About BloomStruck Hydrangea® | Endless Summer®

Endless Summer is well-known for its collection of reliably beautiful, reblooming Hydrangeas, and the Bloomstruck Hydrangea is no exception! Dr. Michael Dirr of Plant Introductions, Inc. first bred this remarkable hydrangea, and gardeners across the nation have taken notice rapidly. It has a neat mounding growth habit of dark green foliage that reaches 3-4 feet across with a spread of 4-5 feet. It produces rose-pink, purple, or blue mop-head blooms that grow 3.5 – 5 inches across. Like other Macrophylla Hydrangeas, you can change the color of your blooms by raising or lowering the pH level of your soil. More acidic soil will bring out the violet-blue tones in the blooms, and more alkaline soils will produce rose-pink blooms. Although capable of several colors, it’s most noted for rich violet-blue flowers that truly separate it from the pack. Enjoy the gorgeous blooms all season long, as this landscape treasure continuously reblooms from spring to fall.

This selection produces strong and beautiful red-purple stems that add a fantastic contrast to the dynamic, rich flowers. BloomStruck Hydrangeas are renowned for their ability to bloom on old and new wood!

*The BloomStruck Hydrangea® is a deciduous/semi-evergreen plant and will go dormant during the winter months. When this plant is ordered during the Fall/Winter expect seasonal foliage decline(discoloration, spots, leaf drop) or the plant to arrive completely dormant.*

Endless Summer Bloomstruck Hydrangea Care

Hardy from Zones 4-9. This is a notably cold-tolerant plant. However, much of this is due to the fact that it is a deciduous plant. Therefore, it will lose its leaves after the first freeze of the year and come back with new growth in spring.

Plant the Bloomstruck Hydrangea in partial shade in all zones. However, these Hydrangeas can handle some direct sun. Gardeners in the Northern US can allow around 3 hours of direct sun, while gardeners in the Southern US won’t want to allow more than 1-2 hrs of unfiltered sunlight. Err on the side of caution as they are very susceptible to burning with too much direct sun exposure.

Hydrangeas need constant moisture to thrive, therefore supplemental watering may be necessary to ensure their success in times of drought. In addition, we recommend watering them a couple of times per week while the plant is establishing itself. This will help it establish deep roots that are able to tap water from deep in the soil.

Standing water will cause root rot and the rapid demise of this plant. Consequently, well-draining soil is essential.

We recommend fertilizing with a slow-release fertilizer in late spring or summer. Furthermore, fertilizers with a balanced NPK ratio will work, however, you may want to choose a fertilizer that is higher in Phosphorus. This will encourage increased bloom production.

How to Plant Your Bloomstruck Hydrangea

Dig a hole three times the width of the pot that your plant came in. The hole should be deep enough that the top of the plant’s root ball is even with or slightly higher than the ground around it. Mix your native soil with some rich garden soil to provide additional nutrients for your growing plant. If your soil is clay-rich, we recommend mixing pine bark in with your native soil at a ratio of about 1:1. Fill the hole back up with your native soil mixture. We also recommend applying 3-4 inches of mulch around the base of your plant to help it retain moisture.

Endless Summer Bloomstruck Hydrangea Spacing Recommendations

For a continuous hedge, space your plants 2.5-3 feet apart. This will allow their branches to grow together nicely as the plant matures, and allows for maximum foliage density. For space between plantings leave 5+ feet between plants.

Recommended Companion Plants

Pair this variety with other partial shade plants that contrast with either color or foliage texture.

The Florida Sunshine Illicium thrives in similar conditions to the Bloomstruck Hydrangea and its foliage contrasts beautifully. It’s bright golden-yellow in hue and evergreen, with elongated upward-facing leaves.

Try planting it with a Camellia bush or two, like the Christmas Carol Camellia or Shi Shi Gashira Camellia. Both of these varieties bring great bloom color contrast and evergreen foliage that are sure to impress.

The Soft Caress Mahonia has dynamic feathery foliage that really shines in a partial shade garden. It also has bright yellow flowers in early winter.

    I’m very pleased with the Bloomstruck Hydrangeas. The plants arrived on time and in great condition. I will purchase from Plants By Mail again.

  2. Beautiful Garden (verified owner)

    So glad I found Plants by Mail. The hydrangeas arrived in excellent condition; they’ve been planted in pots and look healthy and happy. Thank you for excellent quality; I will consider ordering from you again.

    I purchased 3 Endless Summer BloomStruck Hydrangea and 3 Endless Summer Blushing Bride, they were beautiful packed and quality plants. Unfortunately from shipping and acclimating to Ithe new environment they started to lose their leaves. I called customer service and spoke to Christie twice. She was very patient and helpful on explaining that it was expected that it would happen. They are planted and my hope are they will bounce back to how beautiful they arrive. I will order again for quality and service. Thank you

    A little wilted but I planted it immediately and it sprung right back. Very nice plant.

      Yes mam. The hydrangeas are very emotional plants. They like dropping when they want water and don’t care who sees it. But they also quickly perk up with care, sunlight, and water. I’m glad you’re happy with your plants. – Christy

  5. Bryan Houser (verified owner)

    Plants arrived very healthy and much larger then I expected. I Have seem similar plants in the stores that don’t look as good for more money.

  10. Delilah Burhyte (verified owner)

    I was expecting a plant with flowers, so I could see what kind it is. But it’s all stem, hopefully the plant will bloom soon.

    • Team PBM

      Good morning. Yes, the Hydrangeas are a deciduous plant, meaning that it sleeps for winter. They will be waking up shortly.

  11. Brenda Lavin (verified owner)

  12. Susan Combs (verified owner)

    I ordered 2. They were big, healthy, and beautiful. They adapted well and are setting buds.

  13. Margaret (verified owner)

    All 6 plants arrived in excellent condition. They are ready to bloom and I anxiously await the colors.

  14. af50613 (verified owner)

    I am so happy with how well this plant performs. It was blooming soon after arrival. And it has been going strong ever since. I held back my enthusiasm because I cannot remember receiving plants in the condition released from your company.

  15. Larry W (verified owner)

    I just received my Bloomstruck hydrangea in the mail yesterday. This is my first time ordering plants by mail. I am impressed by how they packaged the plant. It was labelled appropriately. I ordered a 1 gallon Bloomstruck. The plant was healthy and moist. I am very pleased with this purchase!

  20. Teresa Henke (verified owner)

  21. Pattie Tierney (verified owner)

    All I can say is, WOW! These far exceeded my expectations, and are thriving. I immediately told a friend about these beauties, she placed an order for the same plants, and was equally pleased. I will definitely be ordering again. Thank you so much.

  22. Susan (verified owner)

    Better Than the Nursery!
    I ordered 21 endless summer Bloomstruck hydrangea and each and every one looks full, green and has the start of green blooms. Nicer than the local nursery and big box stores I just went to a couple days ago and a better price with the quantity discount. They came well packaged, well watered. If all the plants are are nice as these PlantsBy mail is a gardeners dream. Delivered a day early by FedEx. I’ve been gardening for 25+ years so I can say that these are quite nice and delivered to my doorstep! Open the box top, push the four plant holding cardboard placeholders out, open the bottom and slide the plant all the way out from the bottom of the box. Remove the plastic bag that keeps the soil neat during transport, water and you are good to go. Recommend this mail by order plant store. Wuhoo!

    Now what else can I order………

  24. victoria.m.clair (verified owner)

    Ordered in late spring and held a week or two until last frost. Plant is definitely establishing now (midsummer) and has begun to rebloom however the blooms at this point are much smaller than my other hydrangeas. Will update review if blooms are larger next year. Would still recommend and still satisfied.

  25. levi_abrenica (verified owner)

    I ordered this in a 2 gallon container. The plant came well packaged and healthy but small for a 2 gallon size. It is more appropriate for a 1 gallon container. A little disappointed.

    These look absolutely awesome when they arrive. Make sure to follow instructions and take them out of the packaging and remove the plastic as soon as they arrive. Need a lot of water at first. Great buy.

  27. Jennifer Lemke

    I was a little skeptical to order from online but I am REALLY glad I did! The Bloomstruck Hydrangeas I ordered came very quickly and were huge and beautiful!
