Hydrangeas That Grow in Zone 5

Cold hardy hydrangeas are not hard to find as most varieties survive very cold winters.

I’ve been looking for a new hydrangea to add to my yard and that means it will have to thrive in zone five.  I live in the Monadnock Region of southern New Hampshire and that is Zone 5, or 5a, to be more specific.  These are cold hardy hydrangeas, and luckily most varieties of hydrangea can take the extreme cold.

I can tell you (and show you) what I have presently growing in my yard, and these types are found frequently in my area of the country.

The Endless Summer Blue macrophylla (rounded flowers) variety is popular for it’s beautiful blue flowers.  As you can see in the photo below, this type can grow flowers in shades of pink, purple and blue all on one shrub!  Gorgeous.

See more photos.

More types of hydrangeas I’ve grown in my New Hampshire yard with much success include the “Blushing Bride” which is also an Endless Summer variety.

Also, Pinky Winky and  Pee Gee (Paniculata grandiflora), and many others will grown in the north.  In fact hydrangeas seem to enjoy cold more than heat.  The Endless Summer types tend to wilt in the hot sun, even if they have plenty of water.

My best advice is to shop in local stores and nurseries in spring and see what they are selling.  Most likely the types for sale will do well in your climate zone.  Also, you can view a comprehensive list of Hydrangea types and their grow zones on Dave’s Garden site.

One warning about planting the Pinky Winky (which is one of my favorites, and is featured at the top of this page, in pink) is that deer will eat it.  One side of my shrub was always chewed down where the deer passed through my yard!  It also attracts bees, so maybe keep it away from patios and outside sitting areas.  But it is very easy to care for, and it produces gorgeous flowers. So please don’t let that stop you from including one in your landscape.

Some of My Blue Flower Pictures

If you are looking for blue flower pictures – I mean REAL blue flowers, today I am showing off some of mine.

How many times have you seen a purple flower listed as being blue. In the flower kingdom, this happens a lot and I think it is because there really aren’t that many true blue flowers.

It’s a popular color, especially for weddings – that “something blue” phrase can be taken care of with a blue bouquet or at least one blue flower in the mix.

Blue flowers are popular in the landscape too. The perennials that come in blue are certain types of hydrangea (pictured), such as the “Endless Summer” variety.  But soil must be acidic for flowers to be nice and blue.

I also love the forget-me-not, which sports tiny bright blue petals with yellow and white centers.

Another flower I grow that is sometimes blue is the Columbine.  I love the variety of that plant and I’ve had light blue flowers, but the more common color is dark purple, as you can see in my photo below.  My images are not free to use, so please contact me if you want to use one, with a link back to my blog.
