The Nantucket Blue™ Hydrangea (Hydrangea macrophylla 'GRENAN') is a great new Hydrangea and is a repeat blooming selection of the renowned Bigleaf Hydrangea that adorns houses on the island of Nantucket. Unlike most Hydrangeas, this unique beauty blooms repeatedly on new growth throughout the growing season and may bloom from early summer well into early fall.

Dense leathery green foliage provides contrast for an abundant summertime display of blue or pink mophead clusters that rebloom on new wood and last until frost. Not only will you enjoy Nantucket Blues™ gorgeous blooms all growing season long, but shade gardens can become a sea of blue throughout USDA growing zones 5-9.

These Hydrangeas are pH-sensitive and will change color depending on the acidity or alkalinity of your soil. It is best to sweeten the soil with lime to turn the blooms pink. Or acidify the soil to intensify the blue!

Planting and Application:

It only takes a few of these beauties to fill up a garden bed. They quickly grow to 6 feet high and just as wide every year. They make great statement plants in your front yard under trees. They also thrive as foundation plants or backing up a classic cottage border. Use as foundation plants or hedges, backdrops to the garden, or create lovely screening around seating areas.

A single Nantucket Blue™ specimen among your Cottage garden or mixed shrub border adds a pop of color in the shade, while a pair of sentries on either side of your front entry stairs, or astride your driveway is a welcoming sight! A ring of these around your patio table will ensure you have guests joining you for dinner all summer long. Don't forget about the armloads of blooms you'll be bringing into your home, too! One Nantucket Blue™ flowerhead can fill a vase!

#ProPlantTips for Care:

Bigleaf Hydrangeas grows best in afternoon shade or in the dappled sunlight beneath large trees. Planting on the east or north side of a home also works well! In cooler climates, Nantucket Blue tolerates some full sun. With Hydrangeas the right amount of watering is important! You must never let them dry out and they prefer to be planted in enriched moist, well-drained soil. Add a layer of mulch over the soil's surface for further insulation and moisture retention. Blooms on both old and new wood, near and far from the coast, it is recommended you prune in early spring as you see new growth emerging. But be careful to only snip back anything that died during the winter.

Big beautiful blooms in the classic blue color and rounded form, the Nantucket Blue™ is perfect for adding huge bursts of color and curb appeal to your home and landscape! Hurry and order this garden standard from the Hydrangea experts at NatureHills.com!

Long blooming

I planted three of these in a group by my shade tree, and they sure added color to that shaded area. Easy to take care for, but do need consistent watering.

Hello Sal,

Thank you so much for sharing your wonderful experience with your Nantucket Blue™ Bigleaf Hydrangeas! We’re delighted to hear how beautifully they’ve enhanced the shaded area by your tree—those splashes of color truly brighten up any space. You’re absolutely right that these hydrangeas appreciate consistent watering, especially in shadier spots where soil moisture can sometimes dry unevenly. A good tip is to maintain a layer of mulch around the base to help retain moisture and keep the roots cool.

If you ever want more suggestions on keeping your hydrangeas thriving—especially during hotter, drier spells—don’t hesitate to reach out. We’re always here to assist with care tips or seasonal guidance!

Hi Sal,

Thank you so much for sharing your experience with the Nantucket Blue™ Bigleaf Hydrangea! We’re delighted to hear that planting three of these by your shade tree has brought vibrant color to that area. You’re absolutely right—while they’re relatively easy to care for, consistent watering is key to keeping those blooms thriving in shadier spots.

If you haven't already, mulch around the base of your hydrangeas to help retain moisture and regulate soil temperature—this can make watering easier and more effective. Also, feeding them with a balanced, slow-release fertilizer during the growing season can boost their blooming potential even further.

We love hearing how our plants are enhancing your garden, so please don’t hesitate to reach out if you have any questions or want additional care tips!

Bloom period

If I keep the Nantucket Blue hydrangea well watered it will bloom until fall. I let it dry out once and it quit blooming for the whole summer. Wonderful blue blooms.

Dear Sara V,

Thank you so much for taking the time to share your experience with the Nantucket Blue™ Bigleaf Hydrangea! We're delighted to hear how beautifully your hydrangea blooms when given consistent care and proper watering. Your observation about the drying out affecting the bloom period is spot-on—these hydrangeas thrive when their soil stays evenly moist but not waterlogged.

To help maintain those vibrant blue blossoms into the fall, you might consider using a layer of mulch around the base of your hydrangea. Mulch helps retain moisture and regulate soil temperature, which supports sustained blooming. Also, watering deeply but less frequently can encourage stronger root growth. If you ever want to ensure your plants are tenderly cared for, feel free to check out our plant care guides and watering tips available on NatureHills.com—they’re full of helpful suggestions tailored to your specific hydrangea.

Thank you again for your thoughtful feedback and for trusting us with your gardening journey. We hope your enchanting blue blooms continue to brighten your space well into fall!

Hi Sara,

Thank you so much for sharing your experience with the Nantucket Blue™ Bigleaf Hydrangea! We're thrilled to hear how beautifully those vibrant blue blooms respond to consistent watering. You’ve made such an excellent observation—hydrating your hydrangea regularly is key to prolonging its flowering period, and letting it dry out can definitely set back blooming.

If you’d like, using a mulch layer around the base of your hydrangea can help retain moisture and reduce watering needs, especially during hot summer months. Also, watering in the early morning can be more effective and gentle for the plant. Should you have any questions about fertilizing schedules or pest management to support continuous blooms, feel free to reach out anytime!

Thank you again for taking the time to share your success—it’s wonderfully encouraging for other plant lovers too.

Wishing you happy planting,
The Nature Hills Plant Experts

Blue flowers

The Nantucket Blue hydrangea needs an acid soil to keep the flower blue and a lot of moisture in hot summers.

Hello TJ,

Thank you so much for sharing your experience with the Nantucket Blue™ Bigleaf Hydrangea! We truly appreciate your insightful note about the need for acidic soil and ample moisture during the hot summer months to maintain those beautiful blue blooms.

To help achieve and sustain that perfect acidity, you might consider using soil amendment products like elemental sulfur or monitored applications of aluminum sulfate, which are commonly recommended to lower pH levels. Mulching around your hydrangea also helps retain moisture and keeps roots cooler during heat spikes. Additionally, regular watering—especially during dry spells—can make a big difference in keeping your plant happy and vibrant.

Please feel free to reach out anytime with questions we may assist with or if you'd like tailored advice for your gardening zone—we’re here to help!
