Evergreen shrubs come in a variety of shapes, from rigid pyramidal formations to irregular, low-spreading bushes. If you are looking for pyramid-shaped evergreens for your lawn or garden, you can choose among many options. But before you do any planting, consult a hardiness zone map (see Resources) to help you decide which shrubs are best suited to your climate.
American arbor vitae is either a small tree or a large shrub depending on which variety you choose. It varies greatly in size, shape, colour and texture between cultivars. These include Holmstrup arbor vitae, which has a compact pyramidal form; Siberian arbor vitae, with a dense, more broad pyramid-shape; and Techny arbor vitae, a more loosely-growing pyramidal shrub. They are usually cold-tolerant, hardy to USDA zone 3, and prefer moist but well-drained soil with full or partial sunlight. Young shrubs may be susceptible to winter burn in snowy areas, so consider providing shade at this time of year.
Dwarf Serbian Spruce
Hardy in zones 4 through 7, dwarf Serbian spruce is a slow-growing shrub that grows 3 to 6 feet tall with an irregular pyramidal shape. Sun to partial shade is best; dwarf Serbian spruce prefers well-drained soil with medium moisture. It is more tolerant to heat and humidity than most spruce varieties, though it may be susceptible to wind damage. It sports short, stiff glossy-green pine needles and egg-shaped pine cones.
A native of China and Japan, this juniper is available in various cultivars. Most are hardy in zones 3 through 9, though not all can tolerate the temperatures of zone 3. Blue point juniper is a pyramidal cultivar that has an upright formation with dense, blue-green foliage. Usually reaching a height of about 8 feet, it is commonly used as an accent or as a hedge shrub. Most Chinese Junipers prefer full sun, though some will tolerate partial shade. Moist, well-drained soil is best; this shrub is drought-tolerant once established, but should be watered regularly when young.
