Hilograss (Conjugatum)

The Hilograss (Conjugatum) is generally described as a perennial graminoid. This is native to the U.S. (United States) has its most active growth period in the year round . The greatest bloom is usually observed in the indeterminate, with fruit and seed production starting in the year round and continuing until year round. Leaves are retained year to year. The Hilograss (Conjugatum) has a long life span relative to most other plant species and a rapid growth rate. At maturity, the typical Hilograss (Conjugatum) will reach up to 3 feet high, with a maximum height at 20 years of 0 inches.

The Hilograss (Conjugatum) is not commonly available from nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed, sprigs. It has a rapid 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 15°F. has medium tolerance to drought and restricted water conditions.
