Thank you gardengal. In that case, I will try All summer beauty and see how it works out.

Endless Summer is a series of hydrangeas, the individual introduction you are talking about is The Original ('Bailmer').

About Endless Summer Hydrangeas From Bailey Nurseries

Be that as it may, the "Original" was known just as Endless Summer for a half dozen years before there was any series with other introductions under that moniker and is still widely known and sold by that name to this date and will continue to be. When one refers to an "Endless Summer hydrangea", everyone knows which Endless Summer they are referring to!!

Since these are all registered trademark names anyway there is no need to get pedantic about it.

i appreciated the information, Embo!

I grew All Summer Beauty about 20 years ago. I got maybe a couple of blooms on new growth and no repeat blooms. I've had bad luck with endless summer too. I avoid macs because they just don't bloom reliably in my zone 7a yard.

Endless summer is the same as Hydrangea Semperflorens (old variety)

I am not entirely clear what the intent of the previous comment is but Endless Summer, The Original is NOT the same as Hydrangea Semperflorens. In fact, Hydrangea Semperflorens is not recognized as a legitimate cultivar name by any Hydrangea resource or authority.

Endless Summer, The Original is the first reblooming or new wood flowering macrophylla to hit the horticultural world and be acknowledged as a legitimate, registered cultivar.

That's not thrue,

There was a court case between Bailmer and Pieter Zwijnenburg, and Bailmer lost the case

He could provite no evidence that Endless Summer was different from Semperflorens

There are more old spieces flowering on new wood like Ave Maria (The best one flowering)

Endless summer was a nice marketing strategy

We have a big collection standing here more than 700 species Hydrangea's

and semperflorens standing here more than 50 years

As I stated, since Hydrangea Semperflorens (or more correctly, Hydrangea macrophylla 'Semperflorens') is not recognized by any hydrangea resource or authority as a legitimate cultivar, I find that very difficult to accept. Why is there virtually NO published literature on this so-called "old" variety?

btw, I could also find NO evidence of a lawsuit involving Endless Summer. Anywhere. Not sure what Pieter Zwijnenburg has to do with anything - he has zero connection to either cultivar. And FWIW, Bailmer is the registered cultivar name for Endless Summer, not a person.

The previous poster is looking more like a spammer/troll than someone with actual valid or substantiated horticultural knowledge to share.

I knew Pieter Zwijnenburg and he was not lying

Who is the spammer/troll ??

Sorry but that is not supportable evidence. And/or is grossly out of date. There is no mention of Semperflorens anywhere on the Esveld website. Nor is there any locatable documentation to support the notion that Pieter Zwijnenburg had anything to do with its introduction.

Still not buying this without better documentation/proof.

Standing in this book written by van Gelderen ( company name Esveld )

We working with Firma Esveld

Look under the name Hydrangea macrophylla semperflorens ( bailmer endless summer)

" Look under the name Hydrangea macrophylla semperflorens ( bailmer endless summer) "

I did.......multiple times. Absolutely nothing turned up that associated those two distinctly separate cultivars together. Nor any of the other allegations you made.

Seems real to me.

Because it may be referred to in a couple of dated European websites does not give it much veracity if it is not included in any global hydrangea references. And it is not! That omission is very telling.
