    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    These conifers are members of the cypress family which includes many ornamental and timber genera. The common name is Arborvitae or Tree-of-Life due to its evergreen quality in the face of adversity as well as the medicinal properties of its sap, bark and twigs. There are five species native to North America and Eastern Asia with only three of these in cultivation. T. occidentalis is probably the most widely cultivated and is indigenous to a large range in eastern North America, most notably in wet forests and swamps. It was first cultivated in 1534 and the oldest known living specimen is thought to be over 1000 years old. This plant is attractive to deer who like to feast on the soft, winter foliage.
