Landscape Attributes

Aristata Formal Form is recommended for the following landscape applications;

• Accent
• General Garden Use

Planting & Growing

Aristata Formal Form will grow to be about 20 feet tall at maturity, with a spread of 25 feet. It has a low canopy with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live to a ripe old age of 300 years or more; think of this as a heritage tree for future generations!

This tree should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is not particular as to soil type or pH. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. This species is native to parts of North America.
