Big Quakinggrass (Maxima)

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

The Big Quakinggrass (Maxima) is not commonly available from 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 47°F. has medium tolerance to drought and restricted water conditions.
