At maturity, the typical Redbay (Borbonia) will reach up to 70 feet high, with a maximum height at 20 years of 50 feet.

The Redbay (Borbonia) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor.
