The Bluegreen Saltbush (Nummularia) is generally described as a perennial shrub. This is not native to the U.S. (United States) and has its most active growth period in the spring and fall . The greatest bloom is usually observed in the winter, with fruit and seed production starting in the winter and continuing until winter. Leaves are not retained year to year. The Bluegreen Saltbush (Nummularia) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Bluegreen Saltbush (Nummularia) will reach up to 9 feet high, with a maximum height at 20 years of 9 feet.

The Bluegreen Saltbush (Nummularia) is easily found in nurseries, garden stores and other plant dealers and distributors. 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 -8°F. has high tolerance to drought and restricted water conditions.
