At maturity, the typical Elephant Grass (Purpureum) will reach up to 10 feet high, with a maximum height at 20 years of 0 inches.

The Elephant Grass (Purpureum) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by cuttings, seed, sprigs. 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 17°F. has high tolerance to drought and restricted water conditions.
