Sand Ryegrass (Arenarius)

The Sand Ryegrass (Arenarius) is generally described as a perennial graminoid. This is not native to the U.S. (United States) and has its most active growth period in the spring and summer and fall . The greatest bloom is usually observed in the mid spring, with fruit and seed production starting in the spring and continuing until summer. Leaves are not retained year to year. The Sand Ryegrass (Arenarius) has a long life span relative to most other plant species and a rapid growth rate. At maturity, the typical Sand Ryegrass (Arenarius) will reach up to 3 feet high, with a maximum height at 20 years of 0 inches.

The Sand Ryegrass (Arenarius) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed, sprigs. 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 7°F. has medium tolerance to drought and restricted water conditions.
