Chalet Swiss Stone Pine is recommended for the following landscape applications;

• Accent
• Vertical Accent
• Mass Planting
• Hedges/Screening
• General Garden Use

Planting & Growing

Chalet Swiss Stone Pine will grow to be about 35 feet tall at maturity, with a spread of 20 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 60 years or more.

This shrub 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 highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America.
