I can't remember ever seeing Hydrangeas blooming in November.  But, I've never grown my own, so maybe I'm not really qualified to say.  

 

I do love seeing these when we walk by Nancy's.  They are so cheerful.  Do you know about color changes in the blooms of some Hydrangeas?

 

If the soil is acid:  the blooms will be blue.  If the soil is alkaline:  the blooms will be pink.  And if the soil is neutral:  the blooms will be white.  Sometimes, when the soil is in transition from alkaline to acid, the blooms will be both blue and pink, looking sorta purple.  

 

See that pinkish blossom in the picture?  It isn't pink because of the soil, it is in the process of fading.  It started out blue, like the others.  Hydrangeas make really good dried flowers, cut at this stage of fading.  

 

Remember the Hydrangeas in Nanny's back yard?  And the story that Granddaddy pounded rusty nails into the ground to make them turn blue!!!  I love it!!!

 

HAPPY GARDENING!!!
