REPORTING WINTER'S IMPACT ON HYDRANGEAS PART TWO
This is the second of two reports on winter's impact on my hydrangeas. A brief recap here. In my last post, I detailed how I went out in May to assess winter's damage, fearing the worst. We had had a 2 week stretch of exceptionally cold winter weather which typically freezes the flowers buds that sleep in the stems of hydrangeas that bloom on old wood.

So now it's time to tell you what happened to my mountain hydrangeas, botanically known as hydrangea serrata. A little background here. Mountain hydrangeas are so called because they come from the mountains of
The best part of that heritage is that they are better adapted to sustain cold
climates and winter conditions. Which is just dandy for those of us who have to
put up with Mother Nature's challenges. Korea
Unlike my bigleaf hydrangea macrophyllas, every single one of my mountain hydrangeas had flower buds on them, regardless of where they were sited. Some had a little tip dieback as shown in this photo, but none had total stem dieback.

My first inspection tour was on May 3 (after one of the coldest Aprils on record) where my heart leapt when I saw signs of life on serrata stems. Then on June 3, those little "broccoli" heads were clearly there as seen in this photo below of Hydrangea Serrata Tiny TuffStuff™:

I had a "mummy" on one tip of this Hydrangea Serrata TuffStuff™ (a mummy is a bud from last year that didn't open and froze on the plant during winter). Now, this plant's reblooming power is producing flowers all along the stem as shown in this next close up photo:
But the best surprise of all is a relatively new acquisition, Hydrangea serrata 'Hallasan’, sometimes listed as 'Spreading Beauty'. It is native to the
And it has just begun to flower as seen on July 3:
This plant is pH sensitive so one can change the color of the flowers if desired. But I don't need any more to do and since this plant is growing near the alkaline foundation of the house, it will most likely stay on the pink side which is just fine with me.
I am excited to use this small dependable hydrangea in other places, especially as a substitute for perennials. It is small enough to do a great job with no maintenance at all. But be warned that it is hard to find. You will have to use your search engine to seek it out but if we gardeners persist, the market may just respond and deliver for us.
My conclusions from this past winter's experiences are two:
First as discussed in part one of my report: reblooming hydrangeas are the better way to go if you have a choice and especially if you garden in zone 5 or colder or if you garden where you can have an unpredictable cold snap. Where the tips of my plants died back, if they have reblooming capability they will generally produce flowers before the season ends. In some cases, those are the flowers I am seeing now. And if you don't garden in a cold climate, magical rebloomers can give you continuous flowering. What's not to like?
Second, mountain hydrangeas (serratas) and especially the rebloomers are as close as you can get to a foolproof mophead/lacecap look-alike. That mountain heritage makes them tough as nails and now with a reblooming gene thrown into the mix, they are unstoppable. That is what is making Endless Summer®BloomStruck® such a winner: it is part serrata AND a rebloomer. This is what BloomStruck® looked like on July 2:

For my small part, you can listen to me on the radio or speak with me in person.
On Saturday morning, July 7, I will be a guest on IheartRadio with C.L.Fornari, The Garden Lady. C.L. hosts a weekly radio call in show. The program is called GardenLine and is broadcast every Saturday morning on WXTK – 95.1 FM, from 8:00 to 10:00 AM Eastern time. You can also hear GardenLine streamed on WXTK.
