Fragrant Mountain Sweet Box is recommended for the following landscape applications;

• Accent
• Mass Planting
• General Garden Use
• Groundcover
• Container Planting

Planting & Growing

Fragrant Mountain Sweet Box will grow to be about 3 feet tall at maturity, with a spread of 4 feet. It has a low canopy. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 30 years.

This shrub does best in partial shade to shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.

Fragrant Mountain Sweet Box makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
