The greatest bloom is usually observed in the early summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Spike Muhly (Wrightii) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical Spike Muhly (Wrightii) will reach up to 2 feet high, with a maximum height at 20 years of 0 inches.

The Spike Muhly (Wrightii) is easily found in 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 medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -18°F. has medium tolerance to drought and restricted water conditions.
