The Seashore Bluegrass (Macrantha) is generally described as a perennial graminoid. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The greatest bloom is usually observed in the late winter, with fruit and seed production starting in the spring and continuing until spring. Leaves are not retained year to year. The Seashore Bluegrass (Macrantha) has a moderate life span relative to most other plant species and a slow growth rate.

The Seashore Bluegrass (Macrantha) is not commonly available from nurseries, garden stores and other plant dealers and distributors. It can be propagated by 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 24°F. has high tolerance to drought and restricted water conditions.
