Being Extremely Cold Hardy Able To Live In The Drastically Cold Temperatures Of Zone 1 As Well As The Warmth Of Zone 8?s Climate, They Can Thrive In A Large Variety Of Areas. They Are Popular As Specimen Trees In Homes, Parks, Commercial Sites, Being An Evergreen Conifer With Dense Branches, They Also Make An Excellent Windbreak.
