Broadleaf evergreens are plants with wide foliage that remains year-round although some evergreens may change colors during the fall. A broadleaf evergreen shrub, Buxus "Green Gem" has a slow growth pattern with a rounded globular form. This 2-foot tall plant has a width that equals its height and features deep lustrous green foliage that keeps its color during winter. The Japanese holly "Golden Gem" (Ilex crenata) is a male cultivar that grows to heights of 1-1/2 to 2 feet with a matching width. This dwarf Japanese holly has elliptical- to oblong-shaped, golden-toned foliage. Small greenish-white flowers bloom during the spring.
Evergreens are species of plants with thin, sometimes needle-like, leaves that stay green throughout the year. "Little Gem" pendula (Picea abies) is a dwarf variety of Norway spruce. Growing to a height of 2 feet, with a spread of 2- to 3-feet in width, this cultivar has a thick, flattened, bun-like appearance. This evergreen produces light green, new growth that matures into shiny, deep green needles. A species of narrow-leaf evergreen with slender scaled leaves is the "Little Gem American" arborvitae (Thuja Occidentalis), a dwarf variety of the white cedar tree. This 3-foot tall shrub has a rounded habit with dense, dark green leaves that turn bronze in the winter. It features a wide spread that supersedes the plant's height.
Deciduous plants have color-changing fall leaves that die off in winter. The "Yellow Gem" cinquefoil (Potentilla fruticosa) is a small, densely spreading deciduous shrub with a low growth habit. This border plant features red juvenile twigs with grayish-green foliage. The "Little Gem" vine maple (Acer circinatum) reaches heights of 3-1/2 feet with a thick, rounded configuration. Its simple leaves with an opposite arrangement vary in color, from reddish in the spring to green during the summer then orange to red come fall.
Large evergreen shrubs work for borders positioned toward the back of a garden or landscape, such as along a fence or property line. "Little Gem" southern magnolia (Magnolia grandiflora) is an erect, compact shrub with a thick configuration. This 20-foot tall evergreen has a spread of 10 feet. The 4-inch foliage has a deep green and bronze tint that offset the showy, spring-blooming creamy white flowers. "Purple Gem" rhododendron is a 2-foot tall evergreen shrub with a span of 3 feet. Bright purple to violet blooms develop in bell-shaped clusters. This eye-catching plant makes an ideal border for gardens or landscapes with non-flowering plants.
