Ilex latifolia

The lusterleaf holly or Tarajo holly is a large, dense, pyramidal, broad-leafed, evergreen shrub or small tree that grows up to 20 to 25 feet tall and about 15 to 25 feet wide. The leaves are 4 to 8 inches long, dark green, and leathery with serrate margins. Small yellowish-green flowers emerge in the spring. This species is dioecious and both male and female plants are required to produce fruits. The female plant produces fruits if pollinated. The fruits are small red berries that ripen in the fall and persist through the winter months.

This plant is native to Central and Southern Japan and Southern China and is often found growing in broad-leaf forests.

The genus name, Ilex, comes from the Latin, Quercus ilex, for holm oak, and refers to the similarity in the shape of the leaves. The specific epithet, latifolia, is Latin, which means broad leaves.

Plant in full sun to partial shade in acidic well-drained soil. It will tolerate a wide range of soil types including moist to dry. It also tolerates drought, shade, air pollution, poor soils, and clay soils and is easy to transplant. It does have a slow growth rate, but it may not thrive in areas with high heat and humidity such as USDA zones 8 and 9. This holly can be pruned to manage its size. Propagation of this plant can be difficult. Hardwood cutting sometimes root and the seeds can take years to germinate. It is pollinated by bees and is not self-fertile.

The lusterleaf holly is one of the largest growing hollies. From a distance, the leaves may be mistaken for a Southern Magnolia. The shiny, glossy leaves are the largest of any holly. It is an excellent evergreen specimen for the home landscape, and woodland setting, and can also be used as a hedge or espalier.
