Fragrant Flatsedge (Odoratus)

The Fragrant Flatsedge (Odoratus) is generally described as a perennial graminoid. This is native to the U.S. (United States) has its most active growth period in the summer and fall . The greatest bloom is usually observed in the late summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Fragrant Flatsedge (Odoratus) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical Fragrant Flatsedge (Odoratus) will reach up to 2 feet high, with a maximum height at 20 years of 0 inches.

The Fragrant Flatsedge (Odoratus) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by sprigs. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 42°F. has low tolerance to drought and restricted water conditions.
