Slender Flatsedge (Bipartitus)

The Slender Flatsedge (Bipartitus) is generally described as an annual 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 mid summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Slender Flatsedge (Bipartitus) has a short life span relative to most other plant species and a rapid growth rate. At maturity, the typical Slender Flatsedge (Bipartitus) will reach up to 5 feet high, with a maximum height at 20 years of 0 inches.

The Slender Flatsedge (Bipartitus) is not commonly available from 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 medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 32°F. has low tolerance to drought and restricted water conditions.
