At maturity, the typical Grand Eucalyptus (Grandis) will reach up to 160 feet high, with a maximum height at 20 years of 65 feet.

The Grand Eucalyptus (Grandis) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a moderate 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 28°F. has low tolerance to drought and restricted water conditions.
