Jungle Rice (Colona)

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

The Jungle Rice (Colona) is usually not commercially available except under contract. It can be propagated by seed. It has a rapid 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 37°F. has low tolerance to drought and restricted water conditions.
