At A Glance: Dutch Blue Hydrangeas

I did some cut flower arrangements for a client last week; she likes blue.  I thought blue hydrangeas might be just the thing- but  I was not prepared for these.  This is a Dutch blue florist’s hydrangea-wow.  I cannot imagine a hydrangea this color in the garden.  It seems like this shocking blue would be very difficult to make work with other plants.  But if an ultra-blue flowered hardy hydrangea should ever become available in my zone, I would most definitely give it a try.
