I think the macrophyllas that change color depending on the soil ph are more or less the same, depending on where you live of course. They need only two or three hours direct sun with afternoon dappled sun. If Endless Summer doesn't work for you, then PW's macrophyllas won't work for you.

It is not officially out yet. The website does not clearly provide information other than to suggest it may produce a lot of blooms.

I THINK a Mac in yourr zone is a waste of time and money

There are a couple of previous comments that don't hold a lot of water :-) First, it is not reasonable to equate the new generation of reblooming macs with Endless Summer The Original. In fact, it is not even reasonable to equate the later additions to the Endless Summer series with The Original ES! These newer introductions have a much better track record of producing reliable flowering from new or current season's growth. And one doesn't necessarily have to wait until late in the season for it to appear.....refer to luis' comments above.

Second, the improved genetics and more reliable current season's growth negates the suggestion that macs in colder zones (5 &6) are a waste of time and money. If selected from these newer intros - like the Let's Dance series or even the newer ES intros - macs should perform perfectly well, at least with new wood flowering.

iuis Cape Cod plant zone is 7 biig diffffent from 5b

Indeed, HU-55447767.. I am aware of that as I visit New England often. What killed their old wood this year was blamed on unusually large temperature fluctuations. In zone 5b, late frosts or very cold temperatures typically might also kill old wood. But the cause is not exactly important; it is the good/quick response of Can Do's new wood that I find encouraging.

Myself, with something as visible and expensive as a hedge, would go with one that we already know is fully hardy in zone 5.Ask yourself what are qualties of this macrophylia (lets dance something) that cant be duplicated or approximated by any of the many zone 5 hardy hydrangeas.

have you considered Annabells? they bloom early, flowers hold their green color for months the, rock solid hardy, and you cant mess up the pruning

yes they an old hydrangea but they , not a marketing company, sell themselves.

This year’s Cape Cod Hydrangea Festival is in July! Starts July 7.

little lime is frequenyly used for hedges big post on gardenweb showing evolution. dont remember where ir when but probably shrubs or perenniald abit 2 years ago

Let’s Dance Can Do is currently for sale and was reported to have lost all the old wood due to fluctuating temperatures and yet was full of opening flower buds on new wood

Isnt this mostly same description for (all?) the Lets Dance lineup? It is the case for Let's Dance Skyview which I bought earlier this spring.

Yes, there is some similarity in the current lineup. The usual difference is found either in the bloom forms (lacecap versus mophead) or in the plant dimensions.

@Nicole z.5b IL, you could buy one of the PW macs and see if it works for you. My recent success growing macs is because I now grow them in containers and place them in the areas of my garden that only get two hours of direct sun. I put them into a shed/garage during winter. Last season I took them out too early and a cold snap killed the buds and I had to wait for new ones which were okay. This season, I waited until after May to take them and now they are flourishing.
