The Salal (Shallon) is generally described as a perennial subshrub or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer and fall . The Salal (Shallon) has green foliage and inconspicuous white flowers, with an abuncance of conspicuous purple fruits or seeds. The greatest bloom is usually observed in the mid spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are retained year to year. The Salal (Shallon) has a moderate life span relative to most other plant species and a rapid growth rate. At maturity, the typical Salal (Shallon) will reach up to 6 feet high, with a maximum height at 20 years of 1 foot.

The Salal (Shallon) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a rapid ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 7°F. has low tolerance to drought and restricted water conditions.
