The Bigberry Manzanita (Glauca) has dark green foliage and inconspicuous white flowers, with a smattering of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the late winter, with fruit and seed production starting in the winter and continuing until spring. Leaves are retained year to year. The Bigberry Manzanita (Glauca) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Bigberry Manzanita (Glauca) will reach up to 18 feet high, with a maximum height at 20 years of 10 feet.

The Bigberry Manzanita (Glauca) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 12°F. has high tolerance to drought and restricted water conditions.
