Canadian Hemlock
The hemlock, while being a beautiful tree, does not do well in the urban environment. The site needs for the hemlock are usually incompatible with the urban environment. This tree is rarely seen in Minnesota's cities due to this. This tree has numerous insect and disease problems. If you do have a setting that has abundantly moist, well drained soils, is protected from wind, and is partially shaded; this tree will do well.
