It is native to the Rocky Mountains in the United States , enjoy a nerveless and humid climate . The Colorado spruce can withstand drouth and severe coldness best than any other species of spruce .

Warning
Do n’t use a stratification procedure when burgeon forth your Colorado Blue Spruce seed . Stratification , which is placing source in cold temperatures for a geological period of time prior to germination , is not necessary to germinate the seed .
