The Mountain Muhly (Montana) 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 . The greatest bloom is usually observed in the early summer, with fruit and seed production starting in the summer and continuing until summer. Leaves are not retained year to year. The Mountain Muhly (Montana) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical Mountain Muhly (Montana) will reach up to 1.5 foot high, with a maximum height at 20 years of 0 inches.

The Mountain Muhly (Montana) is usually not commercially available except under contract. It can be propagated by seed. It has a moderate ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -38°F. has high tolerance to drought and restricted water conditions.
