MYSTERY FLOWER FRIDAY

Forget what you know about the seasons when flowers bloom, because the world has gone mad.  Guess what flower this is.
.  
Here are some hints:
-it is a woody, deciduous scrub, 
-it usually flowers in early summer
-the flowers can be lavender or deep purple, pink or white
-the flowers have a heavenly scent
-this shrub is often plagued by powdery mildew
-in Minnesota, they are planted as tall hedges in the freeway medians.
  making for a glorious sight!
-this photo was taken today in California, but they are not common here.

I found this blooming in a garden dedicated to this flowering shrub.
Since I could not believe it could be blooming in late November, I
smelled it & knew it is a LILAC BUSH.  

It was the only cluster of tiny flowers on the bush.  Almost all the leaves have fallen off.  The scent was intoxicating.  What a nice surprise!
I will go back in the Spring to see it in full bloom.

PS:  LILAC thrives in Minnesota, where they have brutal winters, but 
I rarely see them here in sunny California.  Its a mystery....
