Landscape Attributes

Brisbane Box is recommended for the following landscape applications;
- Accent

Planting & Growing
Brisbane Box will grow to be about 40 feet tall at maturity, with a spread of 40 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and should not be planted underneath power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 80 years or more.
This tree does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type, but has a definite preference for acidic soils, and is subject to chlorosis (yellowing) of the foliage in alkaline soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America.
