The greatest bloom is usually observed in the early summer, with fruit and seed production starting in the summer and continuing until summer. Leaves are not retained year to year.

At maturity, the typical Sudangrass (Drummondii) will reach up to 2.5 feet high, with a maximum height at 20 years of 0 inches.

The Sudangrass (Drummondii) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by seed. It has a none ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 57°F. has high tolerance to drought and restricted water conditions.
