    Design IdeasThe graceful look of this tree should be on display for all to see in the lawn or an uncrowded part of the garden. Summer blooms and fall color only add to its charm. It can take a little shade fromother trees.
    Companion PlantsFor the layered look, use a groundcover such as Green Sheen Japanese Spurge (Pachysandra terminalis 'Green Sheen') where it will be shaded. Add another layer of shrubs such as Alice Oakleaf Hydrangea (Hydrangea quercifolia 'Alice') or Sunburst Hypericum (Hypericum frondosum 'Sunburst'), yellow flowers of the latter will bring out the yellow color of the stamens in the stewartia.

    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).
