Me again! I am also thinking about Snow Queen. Thoughts?

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!

Thank you, wild! As a novice I go solely by the zone recommendations I find, but most places don't go into detail regarding winter protection. (And I know I won't do that!)

Little Lamb is on my list of possibilities . . .any idea how long it would take to get to at least 4 ft in my zone (5)?

What about Vanilla Strawberry? Would that work?

Thanks, unique! I was not even familiar with Tardiva until I just looked it up now . . .Dharuma sounds great except I want something closer to 4-5 ft, so not sure it would work.

Good to hear about Little Lambs . . .definitely on the list!
