California Oatgrass (Californica)

The California Oatgrass (Californica) is generally described as a perennial graminoid. This is native to the U.S. (United States) has its most active growth period in the fall and winter and spring . The greatest bloom is usually observed in the early spring, with fruit and seed production starting in the spring and continuing until spring. Leaves are not retained year to year. The California Oatgrass (Californica) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical California Oatgrass (Californica) will reach up to 2 feet high, with a maximum height at 20 years of 0 inches.

The California Oatgrass (Californica) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 17°F. has medium tolerance to drought and restricted water conditions.
