Blue Atlas Cedar is a species of evergreen that grows well in zones 6, 7 and 8 throughout North America, particularly in the South, Southwest, and Pacific Northwest. They can be pruned into a conical shape or left to spread out in the classic fur-like style, and are capable of withstanding heat, cold and drought.
Blue Atlas Cedar can be finicky when it comes to planting other plants nearby; the root system does not react well. To that end, it can be difficult to find plants without deep root systems whose foliage complements the cedar's vivid silver-blue.
Mertus are a rounded shrub roughly five feet tall with thick, dark green leaves. They produce saucer-shaped flower petals with fluffy stamens and have a very shallow root system for their size.
Daphne are dense shrubs that grow up to three feet high with woody bark and branches. The leaves all spray from central branches, are long and flat, with yellow rims and olive green interiors. The flowers are white, bell-shaped, and very fragrant. Andromeda is an upright, wide-reaching shrub with understated dark green leaves. They produce a spray of downward-hanging flowers shaped like urns.
Abutilon is more commonly known as Chinese lantern. They grow in a mounded shape no more than three feet tall. The stems are thin and easily broken with leaves like those of a maple. It produces pods which hang down and eventually break open into pink, veinous flowers.
Lunaria is known as honesty or money plant. It produces stems right from the root system, with no central trunk. The leaves are a bronzed brown with raised rims shaped just like coins. The flowers are four-petaled and rise from seedpods (both purple).
The Ceratostigma is a mounded shrub-like perennial which spreads roots just below the ground surface. The rising stems can reach up to a foot high and the plant as a whole tends not to exceed three feet in diameter. The leaves are blade-shaped, glossy green in summer and red-bronze in the summer with deep blue singular flowers. Digitalis is more commonly known as foxglove. They rise on a single stem up to six feet in height, though average three.
From the stem hangs a profusion of bell-shaped tubular flowers in white, blue, pink, or purple. Rhexia have stems in clumps that have pairs of oval leaves along their lengths. They are tipped with branching clusters of four-petaled, rounded purple flowers.
