Boxwoods tend to grow more quickly and can be trimmed into shaped more easily than the other evergreens mentioned here. This variety of evergreen has dense foliage that makes it a good choice for more formal landscaping. These plants can also adapt to almost any soil type as long as they are placed in partial sunlight to prevent them from taking on a golden coloring in winter. One example is the winter gem boxwood. This variety only grows to a height and width of 4 to 6 feet, making it a great evergreen shrub for smaller hedges.
Hemlock comes in tree and shrub forms. Unlike more tolerant evergreens, they will not thrive in compacted or dry soil, but they do tolerate very cold weather extremely well. These evergreens are a bit difficult to establish, but they require very little maintenance once they are. Hemlock is also a more hardy evergreen plant with very few pests or diseases that can cause it harm.
