Some of the "green" hydrangeas do not rebloom. They are Annabelle (note: it may very rarely throw limited blooms in early Fall when it so desires) and its cousins (Incrediball - larger blooms, etc), Limelight or Little Lime. The other white ones may turn somewhat green as the blooms age but there will also be a spill of pink/etc colors too, which I am guessing is not what you want. These will start green and turn white eventually. Less sun exposure will allow the green immature blooms to stay green longer. Some whites that rebloom like ES are: White Out, Blushing Bride (can have a touch of pink/blue on the sepals) and Peace (double blooms, may have a yellow tint sometimes). Lowes has carried White Out and Peace randomly in prior years. Not much selection in local nurseries yet though; too early in the season for that. Some of the white mopheads may temporarily show a tinge of yellow in blooms. Not sure what is all about myself. Paniculatas and oakleaf hydrangeas also bloom white but are not rebloomers. Except for Limelight and LL, most of these may fade from white to a shade of pink. Mme Emile Mouillere (serrated petals) and Sister Therese.(sometimes called Sister Teresa or Soeur Thérèse) are awesome white non-rebloomers... very nice, big shrubs, tough and reliable bloomers. The blooms fade to a mix of colors, not green only though. This post was edited by luis_pr on Fri, Mar 7, 14 at 5:43

Afternoon sun is going to be very restrictive......most hydrangeas would prefer afternoon shade at the very least. If you can, I'd suggest planting on the east or north side of the residence. If you can only plant on the west side, then the only hydrangea type I'd recommend are the paniculatas, which tend to be the most sun tolerant species. Even then, these will need routine deep watering during the summer months. Clay soils are not that difficult to work with provided you go about it properly :-) Dig wide but very shallow planting holes, scuffing up the soil well and plant high. Do not add amendments to the backfill but mulch with whatever you prefer to the top of the rootball.

Lorriekay, At this point, I would NOT recommend Endless Summer. Have 2 on their 3rd season and still not happy with them (and that's putting it mildly) Besides, they are not necessary down here. I understand Luis' logic..longer season translates into repeat blooms, right? That's what I thought might happen but I have yet to see a bloom on 'new wood' on ES and any secondary blooming from old wood is very dismal. I have longer bloom time and even repeat bloom flushes on 'free flowering' hydrangeas than I do on 'new wood' hydrangeas. My suspicion is that 'new wood' varieties only bloom on new wood if the old wood does not survive but that's a discussion for another thread. I have around 45+ hydrangeas currently (and that doesn't count all of the non-performers that I've tossed) and the most RELIABLE, strong, pretty, healthy and adaptable to various sun conditions (very important down here) are, in this order.....(I've chosen 4 different looks/colors) #1...NIKKO BLUE (that's right folks, no typo here, plain old fashioned Nikkos..It costs the least and performs the best. It's what you think of when you think hydrangeas - those big blue or pink snowballs - and can usually be purchased at Lowes or Home Depot very inexpensively. Not trendy but so easy and reliable. Great for beginners... Numero Uno in my yard) #2...Mme Emile Mouillere (a hardy white mophead rebloomer) #3...Blaumeise (kind of new to my garden but so far absolutely fabulous in it's looks, size and vigor; lacecap; not a rebloomer) #4...Ami Pasquier (small dark pink/wine purple blooms; a variety that blooms like crazy) or Alpengluhen or Glowing Embers if you want bigger dark pink/purple blooms (pretty much interchangeable but not as prolific as Ami P) When most people ask about hydrangeas in general, they usually are thinking about the mophead or lacecap macrophyllas so that is what I listed above. However, if you have the space, add an Oakleaf hydrangea or two (or three). In the long run they will be more (but never completely) carefree and very rewarding for a longer period of time. Don't know if you are totally new to hydrangeas or not, but down here they require lots and lots of water as this sandy soil does not retain much moisture. Daily for the first couple of years and sometimes even after. If you just want the pleasure of one or two plants without having to care for them daily, I would highly recommend keeping them in a container (except for the Oakleafs.. they don't seem to like container culture) potted with Miracle Grow MOISTURE RETAINING potting soil. Stuff works great and cuts down on maintenance, big time. Check out 'hydrangeashydrangeas.com' for an excellent tutorial on growing hydrangeas....Good luck....yg

Hello anele- it's great to have another new convert! As far as winter interest goes, unfortunately hydrangeas don't have much to offer, as almost all of them go dormant during the cold months. I would typically recommend Hyd. arborescens (like 'Annabelle') or Hyd. paniculata (like 'Limelight') to my customers in zone 5; or rebloomers like your ES and Blushing Bride. Snow Queen could be a bit of a challenge in zone 5, though it could certainly be done with some winter coverage for the first couple of years, but I think it would want near full sun. You might take a look at one of the dwarf peegees like 'Little Lamb', which will stay smaller than 'Limelight'. You could also try Annabelle or another arborsecens, if you don't have any yet- they are truly gorgeous, tough shrubs- and would be happy with less light than the paniculatas. As far as regular old mopheads, stick to the rebloomers, unless you've got a really protected spot. They are all fairly similar, though, and many of them would look and act just like your 'Endless Summer'. Hopefully this will help some, though- good luck!
