Canada Bluegrass (Compressa)

The Canada Bluegrass (Compressa) 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 . 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 Canada Bluegrass (Compressa) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical Canada Bluegrass (Compressa) will reach up to 2 feet high, with a maximum height at 20 years of 0 inches.

The Canada Bluegrass (Compressa) is easily found in 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 -38°F. has medium tolerance to drought and restricted water conditions.
