American holly

Ilex opaca 'Steward's Silver Crown'

American holly (Ilex opaca 'Steward's Silver Crown') is a beautiful evergreen shrub, native to southeastern United States. It grows in an upright form and produces glossy dark green leaves with white stripes, resulting in a silver crown appearance. The leaves remain on the plant year round and the female hollies produce small, bright red berries that provide brilliant winter color and attract birds. American holly grows best in partial or filtered shade and needs good drainage and rich, acidic soil for vigorous growth and optimal health. An excellent landscape specimen, this holly can easily be trimmed for a formal hedge or left to grow naturally for an informal privacy barrier.

watering

American Holly should be watered regularly. During the growing season, water thoroughly and give it 1 to 1.5 inches of water per week. During hot and dry spells, water more frequently and give extra deep watering to achieve a moist soil. During winter months reduce watering frequency and quantities. Check the soil moisture and only water your holly when the top inch of soil feels dry.

sunlight

American holly (Ilex opaca ‘Steward’s Silver Crown’) does best when grown in full sun to partial shade, meaning that it needs 6-8 hours of direct sunlight each day. In areas with hot summers, some afternoon shade is recommended to reduce the risk of damage from the intense afternoon sun. Generally, American holly prefers a spot that gets morning sun and afternoon shade.

pruning

When pruning American holly (Ilex opaca 'Steward's Silver Crown'), it is best to prune only a small amount, such as removing dead or damaged branches or removing lower branches to create a desired shape. Pruning should be done when the tree is dormant in late winter or early spring. It is best to prune just after the last frost, when new growth is just beginning. Pruning should be done carefully to ensure keeping the natural shape of the tree intact.
