Forked Rush (Dichotomus)

The Forked Rush (Dichotomus) 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 Forked Rush (Dichotomus) has a moderate life span relative to most other plant species and a moderate growth rate. At maturity, the typical Forked Rush (Dichotomus) will reach up to 2.9 feet high, with a maximum height at 20 years of 0 inches.

The Forked Rush (Dichotomus) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, seed, sprigs. It has a slow 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 12°F. has low tolerance to drought and restricted water conditions.
