Hydrangea is a valuable genus of some 100 species of shrubs and vines grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall—a quiet time for most woody plants—and are worth having for that reason alone. For more information on Hydrangea care, click on Growing Guide.

Shipping Info

We want our customers to receive strong, healthy plants that are ready to thrive in their gardens and homes. Here's what we'd like you to know about our shipping practices.

Delivery Timing

We aim to deliver your plants at as close to the proper time for planting in your area as possible. To do so, we consider the USDA Hardiness Zone to which we're shipping, current and forecasted weather at the destination and along the shipping route, and whether your plants are ready for transplant.

In spring, we ship first to the warmest regions and move north as planting conditions improve. For fall deliveries, we begin with the coolest regions and work south. We frequently adjust shipping schedules when extreme weather could put plants at risk while in transit or soon after arrival.

Because different plants reach readiness at different rates and are weather-sensitive in varying degree, a single order may be delivered via multiple shipments. Plants sold as part of a collection, or that are otherwise meant to arrive together, will be shipped together. Please contact our customer service team with two weeks' advance notice if you anticipate being away at the expected time of delivery

Tracking information for each package is delivered via email. 

Plant & Container Sizes

We deliver plants in various sizes and stages of growth, and the product detail pages of our website indicate the form and/or pot size in which the plant will be delivered. Pot sizes range from 1 pint to 1 gallon and larger. Many perennials, roses, shrubs and vines are delivered bareroot - that is, not in a container at all. Bulbs and tubers are generally delivered bareroot and fully dormant. We choose container sizes and delivery methods based on how each plant grows best, how we can minimize transplant shock, and how to minimize unnecessary bulk/weight in shipment. 

Caring for Your Plants Upon Arrival

It is important to acclimate greenhouse-grown plants to life outdoors. All plant shipments include simple instructions for handling your plants upon arrival. Further how-to information, including planting instructions, is available on each plant's product page.

Growing Guide

Latin Name Pronunciation: hye-dran'jee-uh 

Growing H. arborescens

Light/Watering: Most varieties thrive in full sun in the North, but in the South require afternoon shade. Moist soils that do not dry out are best; do not plant in hot, dry, exposed sites. Mulch to conserve moisture and buffer soil temperatures.

Fertilizer/Soil and pH: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15). Soils should be moist but well drained, and rich in organic matter.

Pests/Diseases: None serious. Occasionally powdery mildew will infect the foliage, especially in humid areas with poor air circulation. Treat with an appropriate fungicide if the problem is serious, and be sure to rake up and destroy all fallen foliage in the autumn.

Pruning: In early spring, cut stems back by about one-third their total height, which builds a strong woody base. Hydrangea arborescens blooms on new wood.

Reflowering: You may cut the first flowering stems of H. arborescens and hang to dry for arrangements; rebloom may then occur in August or September.

Transplanting: Young plants may be transplanted when dormant in early spring; larger tree-form varieties are difficult to move once established, but it can be done. Prune top growth after transplanting to reduce water loss.

End of Season Care: Rake up and destroy any fallen foliage that was infected by powdery mildew or other fungi.

Calendar of Care

Early Spring: Cut stems back by about one-third their total height, which builds a strong woody base while also encouraging abundant new growth for lots of flowers and a lush, full look. Feed plants with a fertilizer high in phosphorus (such as 15-30-15) to encourage blooms. Complete any transplanting before leaves unfurl.

Mid-Spring: Mulch plants after soil has warmed to conserve moisture and buffer soil temperatures. Watch for powdery mildew and treat as needed.

Summer: Cut flowering stems from H. arborescens and hang to dry if desired.

Fall: Remove and destroy any fallen foliage that was infected by powdery mildew.

Tough beauties!

"Planted these about a year and a half ago; they produced gorgeous, enormous blooms the first year and have come back for a marvelous repeat performance this summer! They are about 5 ft' tall, stand upright no matter the weather and the blooms never flop. Furthermore, they look as great dried as they do on the plant. Strong recommend for that super classic hydrangea look!"

Hydrangea arborescens Incrediball

"I ordered this hydrangea from WFF in 2013. It is now June of 2022 and all I can say is that it's ABSOLUTELY GORGEOUS. It is now 6 feet high (the height of my fence) and very wide. All I do at the end of the season is cut off the withered flowers, nothing else. It is the centerpiece of my back yard. I planted this in a sunny area of my back yard against a white fence. In the wintertime it just looks like a bunch of sticks protruding from the soil so much so that my son said "why don't you cut down that dead bush." But by the end of March, beginning of April, you can see the buds beginning to protrude from those little sticks. My son was blown away by 'the dead bush.' Every year it is more and more amazing. My best purchase from WFF."

Beautiful Hygrangea

"I bought the flower last fall. This is the first bloomed for me early spring and summer. I can't believed how beautiful they look and how big they are. I will purchase three more this fall."

HUGE AMAZING

"This plant is amazing. 2nd year and ginormous. Wish I could share pics - worth the money. A bit needy in the water dept for the first year or so but worth it!"

Incredibly hardy and strong (careless contractors be damned!)

"Ordered from WFF and planted in spring 2016, two Incrediball hydrangeas are in their second year in my backyard (in a spot with morning sun & afternoon shade). The two bushes produced several large flowers within months of planting and, as promised, their branches did not topple under their weight. Then, in spring 2017, the two bushes were happy and healthy before a crew of careless roofers managed to break both bushes with debris and their trampling feet. I was devastated but, to my surprise, the Incrediballs bounced back within a month's time (they're about 3' tall already) and look as great as ever! So pleased with these strong shrubs!"

Buyer Beware!

"I recently purchased two Incredible hydrangeas with the hopes that the flowers would indeed have strong stems to stand up to rain showers. So far I have been most disappointed in both the stem strength and the size of the flower head Stem strength I see very little difference in the staying power of the stem compared to the regular Annabelle hydrangea. The flowers on the Incrdiball are just as floppy as the Annabelle.Size of Flower Head While the plants I purchased at White Flower Farm were of a good size, the flowers on them are no where near what i would call 'incredible!" Actually, they are quite small compared to the Annabelles that I have blooming! Perhaps this will change in the years to come."

Incrediball

"I purchased this plant 4 years ago from a reputable nursery as a 3 gallon plant just to try it out. I planted it on the northeast corner of my house where it receives plenty of morning sun in soil amended with compost. The first season it was healthy and the blooms were nice but not as advertised. I would say 6" across at the most. The 2nd season it exploded! I measured several blooms at 10" across and a couple closer to 12". The 3rd season the blooms were just a tad smaller in the 7-9" range. Ive never had any trouble with the blooms falling over except after a heavy rain they sag under the weight of the water some but stand back up after the plant dries. Being very happy with this plant I returned to the nursery to buy 2 more to discover they quit carrying them. They said they performed so poorly they stopped selling them and were surprised at how well mine were growing. After searching locally for more with no luck I layered a few limbs from my original plant and transplanted 3 new plants last fall. This spring the original plant is looking as good as ever budding out and the new starts are already about 2 feet tall and even putting out a couple buds on each plant. Very happy and would recommend as long as the plant is sited similarly."

Fantastic! Just like the name

"I live in Ohio and grew three of these at the side of my house. Tons of blooms and they weren't falling over. I had to move and I loved these. Just incredible!!!"

Expert G. (5/5)

Amazing!

"This was the first plant I ordered from White Flower Farm. It arrived in the fall, but I was worried it won't survive. It was skinny, leaves were almost dried up, and just really pathetic. We planted it anyway, deadheaded before winter came, and hoped for the best. This is it's 1st year and it definitely thrived! We had multiple blooms and 90% were big. It got a lot of lookers for sure! I'm debating whether to get another one to plant beside it so it would fill the cove area, but after reading someone's comment that theirs kept growing, I think I will hold off. Maybe it will fill up the cove for its 2nd year!"

Bloom Size is Not Exaggerated

"Purchased two bushes two years ago. Average size blooms the first year and monster size ones the second year on one of the bushes, but the other ones seems to be struggling in comparison (at same location). One bush supplied me with multiple bouquets of flowers for the winter. Has a lemony, citrus fragrance."
