Gaultheria shallon

Salal will grow to be about 4 feet tall at maturity, with a spread of 3 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

This shrub performs well in both full sun and full shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution, 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 species is native to parts of North America.
