|Hydrangea m. Cityline 'Mars'|
I received Cityline 'Mars' from Spring Meadow Nursery as a trial plant last year and immediately cut it back to a height of about one foot. It received the benefit of the Zone Up, another trial from Gardeners Supply. This padded tarp with grommets isn't offered any longer as far as I can find, and I can't really say for sure if it's a loss. It looked like just the ticket when I snugged it around 'Mars' for the winter. But as it turned out to be the winter that never was, I can't say for sure if it worked. I'll try it again next season and see if this tender bigleaf hydrangea blooms as well as it has this year.
Another heat-tolerant Hydrangea macrophylla hybrid from the Color Choice line is 'Let's Dance Starlight', a lacecap that blooms on both old and new wood. I'm pretty sure it's blooming on last year's wood, as it's next to a non-remontant variety called 'Schenkenberg' that is blooming for the first time in at least four years.

Here's a cool thing about 'Let's Dance Starlight': it doesn't wilt as much as other macrophyllas (except for 'Mars', of course. Its leaves are not as thick and substantive as those on Cityline 'Mars', but they certainly don't wilt right along with the flowers as most of the other bigleaf hydrangeas do.
