I'm adding a couple of hydrangeas to this Christmas centerpiece because I love the natural green and the lush cluster of blooms.
Just realize that this water loving flower mayl not last as long as the other flowers (carnations and chrysanthemums) - but can easily be replaced later on with other flowers. Keep the greens well watered and they will last quite a while.
I placed a second hydrangea on the opposite side of the centerpiece.
This top view gives you a better visual of the way I placed the flowers.
