The group of conifers most used in Minnesota is restricted to a few of the "ironclad" sorts. These are all native species and when used the following notes should be borne in mind. The hemlock is not naturally adapted to windswept places anywhere, and especially not in this region. Of the white fir only the Colorado form should be used, and while this plant will withstand considerable heat and drought it is intolerant of smoke and soot. The arborvitae suffers frequently from ice storms and should be protected from them. The Douglas spruce is one of the fastest if not the fastest growing conifer. It produces a soft foliage which requires that it be planted in groups for mutual protection against strong winds.
