This is a Colorado Blue Spruce, in Bonzai form. I purposely gave preferential editing highlight to the reddish intertwined coil. It is estimated to be 80 years old, but the original potting date is unknown. There is one in the back of the picture, that is out of focus, that is older in the top right, it is 150 years old. This is in a Conservatory in Hidden Lake Gardens in Tipton, MI.
