Perfecta Chinese Juniper - Juniperus chinensis 'Perfecta'
Family Cupressaceae – Redwoods, Cypress, Arborvitae, Juniper
These evergreen shrubs or small trees are popular as ornamentals in specimen or hedge plantings. 
Perfecta juniper is fast-growing to 10' tall, spreading to 6 feet. It branches from one low point off a large trunk with scaly, red-brown bark. Perfecta's old growth and new growth is bright green, giving the plant its trade name. The foliage is pungent when crushed. Grey berries are inconspicuous, less than 1/4 inch, and do not pose a litter problem.

This outstanding ornamental grows well even under difficult conditions such as those at urban sites or the seashore. Grows best in full sun, but will tolerate some shade. Likes well-drained soils. Watering is not needed after initial planting.

The Genus Thuja contains five species of coniferous evergreen trees, of small to medium size, and a few shrubs, usually dense.  Bark is scaly.   Branches usually horizontal or also ascending, developing a conical crown.  Twigs more or less flattened.  Leaves opposite, scale-like, appressed, lateral leaves partly overlap facial leaves.  Cones small, ovate or oblong.  Native to North America or eastern Asia.    Many cultivars of different size, form and color are available.  The foliage of several types discolor in winter, reducing their acceptability.  Some tend to thin out with age and attain an unkempt appearance.  Arborvitae are especially popular in the Midwest and eastern U.S.

There is general consensus that one species, Thuja orientalis, does not belong in this genus and has been transferred to the genus Platycladus, hence Platycladus orientalis.  However, most nurseries and retail outlets continue to use the older designation. [1]
