It's probably one of Irie's Japanese hybrids, like Together or You-Me...

Got a pic?

His plants have been the most consistent come-backers as they always die back to 1-2" but shoot up to 2-3' and bloom.

Sorry camera on phone is broken. May have to go get one tomorrow....

could be a Doublicious maybe...

They are selling Wedding Cake at our HD. A double white. Nice but not overwhelming either.

went back and it was on sale!!!

Nice. :) It might be 'Perfection' (Double Delights) if there is a contract between HD and Ball Hort. I'm not sure how the flower head compares to Doublicious, but they are genetically very similar.

And this would mean the white double one is probably Wedding Gown (Double Delights). (I don't believe there's such a thing as H. mac. Wedding Cake.) It's technically a lacecap but looks more like a mop once the bloom has matured.

To all US users: Sadly, these might be restricted to the South Atlantic region, as HD has contracted with Bell Nurseries to sell various items in Vigoro pots. See link provided.

No, the Wedding Cake was a double mop head in a Vigoro container. I have Wedding Gown, Wedding Ring, and Blushing Bride (how many wedding names does one need?)

Huh, no kidding?? I wonder where Wedding Cake originated,

It returned zero search results on the Net, which is odd...

Wonder if it's like Peace. I have two of those, and they're great.

No telling where it originated from. More hydrangeas than ever. I wonder if they are rebranding some old ones.

With a closer look there is a label that says Pink Pefection.

Yep! Thought so. Guess you'll see how close to Doublicious that is. They looked quite similar in photos, but now you'll get to see for yourself.

Here is Wedding Cake at HD this morning. Blooms white and/or pink. Price has been reduce to less than $18 for a 3 gallon.

Looks like Peace to me. :)

May be. That is what I said earlier about rebranding in hopes of more sales...

Yes Pink Perfection here in Williamsburg and Wedding Cake in Hampton!!!

3G Vigoro in my area are ALL... Teller Blue?! One of the least hardy plants for this zone. F - marketing.

Latest Vigiro pot sighting: Zebra. First time I've seen it in this country.

In case people are unfamiliar, this is a black-stemmed, white-flowering plant.

Just look at the interesting growth habit. Already pushing three feet tall with very thick stems and emerald green leaves the size of dinner plates!

Will check HD and Lowes tomorrow.

Would love to find it but not here!
