Sierra False Needlegrass (Kingii)

The Sierra False Needlegrass (Kingii) 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 and fall . 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 Sierra False Needlegrass (Kingii) has a moderate life span relative to most other plant species and a slow growth rate. At maturity, the typical Sierra False Needlegrass (Kingii) will reach up to 1.4 foot high, with a maximum height at 20 years of 0 inches.

The Sierra False Needlegrass (Kingii) 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 -23°F. has low tolerance to drought and restricted water conditions.
