Eastern Red Cedar [highly recommended] - for the Saturn site this is the pre-eminent evergreen tree.  The younger, smaller trees have more acceptable transplanting survival.  It grows fast, is tolerant of drought and disturbed soils, has neat appearance, and retains a dense canopy for year round greenery.  In landscape situations, trees must be monitored for bagworm infestations.  The tree functions well as a wind break.

Virginia Pine [moderately recommended] - this evergreen is extremely hardy and fast growing with a spreading crown when open-grown.  It tolerates drought and a wide range of poor soil conditions.  Problems include tip-moth and pine bark beetle infestations.  The tree can become unsightly after several years due to persistent dead limbs and poor form.

Loblolly Pine [moderately recommended] - although less hardy than Virginia pine, loblolly pine has a taller , more attractive form and fast growth.  Although outside its natural range, this evergreen can grow quite well.  Main concerns are southern pine bark beetle infestations and breakage from snow and ice.

White Pine [moderate to low recommendation] - white pines are attractive evergreen trees with fast growth on good sites.  On poor sites and without maintenance, they may become spindly, slow-growing, and susceptible to disease and air pollution damage.  Middle Tennessee is slightly outside their natural range.

American Holly [moderate to low recommendation] - given good to moderate soil conditions, this broad-leaved evergreen can survive and become quite decorative.  However, in low maintenance plantings they are more likely to have less than a full canopy and be slow-growing.  Survival in Saturn
plantings has been mixed.

Southern Magnolia [moderate to low recommendation] - Middle Tennessee is generally considered outside the range of this broad-leaved evergreen which occurs naturally further south.  Hard winter freezes and summer drought can severely stress the trees.  However, if planted on moderate to good soil, the tree can survive and become a thriving large specimen.  It's large fragrant flowers and dense foliage can create a spectacular effect.
