General Description

Having finely textured dark green needles that blush bronze-purple in winter's cold, 'Glauca' is an upright shrub. Native to the coastal plains of the eastern United States, it has reddish, gray-brown bark that is well hidden by the dense, prickly tufts of needled foliage. Ranging in color from gray-green to dark green with small white bands on undersides, the cold of winter causes leaves to become bronze or purple, one of its best ornamental features. Both male and female cones appear in late spring, being small and rounded. The female cones become less rounded and more scaly as they ripen from dark purple to sienna brown. This tree's foliage is the exclusive larval foodsource for the rare Hessel's hairstreak butterfly.

Grow Atlantic whitecedar in moist, well-draining to soggy soils in full sunlight. Avoid highly alkaline or very dry soils to ensure best foliage. It makes for a lovely foundation plant or can be incorporated into any mixed border to add structure, especially during the winter months.
