Blooms were absolutely gorgeous. But they definitely flopped over. And they never bounced back up like my limelight’s do.

Super-sized flowers!
Incrediball hydrangea will make you say WOW - it's an improved version of the garden classic 'Annabelle' hydrangea, but with strong, sturdy stems that don't flop over and extra-large blooms to boot. White flowers begin to appear in mid-summer and open to enormous snowballs, nearly the size of basketballs! They then age to a lush jade green, which persists through frost. It's a super easy, super reliable North American native that grows in chilly USDA zone 3 all the way up to USDA zone 8/9. Plant Incrediball hydrangea in your landscape and find out for yourself just how big, beautiful, and rewarding it can be.
Top reasons to grow Incrediball hydrangea:
- enormous, long-lasting flowers every summer

Also makes a very dramatic cut flower.
Maintenance Notes:For the biggest, most abundant blooms and strongest stems, plant where it gets at least six hours of sun each day (warmer climates can get away with a bit less). A good layer of shredded bark mulch helps minimize water loss.
As for pruning, cut the entire plant back by about one-third its total height each spring, just as the new growth begins to emerge on stems. This serves to build up a strong, supportive, woody base while also encouraging abundant new growth for plenty of flowers.
If you wish to fertilize, an application of a rose fertilizer in early spring, once the soil has thawed, is sufficient.

Very disappointed, mine died. Was outside the warranty window so could not get refund. I'll only buy from other nurseries in the future, as never had this issue elsewhere.

I have one of these growing under a canopy of trees with dappled sunlight and it is thriving. I love the huge white blooms and I love the green color they turn. It is an elegant shrub that looks heirloom. Love it!

These are absolutely beautiful. I'm very happy with the bush so far. In its first year I'm getting many blooms. The white stays for 1 month at least and have not faded to green yet. They are excellent as a cut flower too. Lots of growth in the first year and I'm looking forward to more. Mine get morning sun and afternoon shade. I water daily on hot days or every other day.

Bought 5 in March. They’ve grown really well. Very lush. And the bloom thus far has been fantastic. Enormous. They’ve been very thirsty and wilt on really hot days (Im zone 8). Given how large they are, I’m hoping they’re growing a root system to support themselves and will need less water once established. Other than needing a bit of babying, they’ve been really beautiful and abundant plants.

Love how light and delicate the flower balls are! The plant is hardy--I shamefully mistreated it the first 3 year by keeping it in a too-small pot. It still bloomed, but small flowers. Then planted in a mostly shady spot. I'm not sure if it gets even 4 hours of sun but this year, after two years in this spot, the flowers look just like the PW website pictures. The shrub itself is still thin so I'll move it to a sunnier spot when dormant. Overall I'm really happy with this hydrangea.

These were sold as a white hydrangea - white for a week or so and now I'm stuck with a hideous ugly sick green flower. Ripping them out next year. New flowers aren't even white - just a uniform sick green.

I planted my Hydrangea Incrediball in the location that gets direct sun from 7 am to 12 pm, zone 6, north east OH, following recommendations about 5+ hours of direct sun. The plant was wilting during hot summer days by 11am even though I watered it regularly and made sure the ground was wet. Last fall I moved it to the shady area that doesn't get any direct sun at all (only dappled sunlight). it's early June now, and my hydrangea Incrediball is covered with flower buds! No wilting and brown leaves. As other people mentioned, the flowers didn't stay white for long and turned into greenish color. I had to stake it because stems weren't strong enough to hold the large flowers last year. Perhaps, the plant needs to mature to have stronger stems.

I purchase two of these about 3 months ago and they are already growing like crazy and have small blooms all over. Great plants!
