Planting & Growing

Green Island Japanese Holly will grow to be about 4 feet tall at maturity, with a spread of 7 feet. It has a low canopy. It grows at a medium rate, and under ideal conditions can be expected to live for 50 years or more.

This shrub does best in full sun to partial shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
