Banksia grandis

This species is very slow-growing and may take 10 years or more to flower from seed. It is very susceptible to root rot both in its natural habitat and in gardens and we have certainly lost many plants to this disease over the years. To combat this problem we grafted Banksia grandis onto Banksia integrifolia which is a much tougher species and is resistant to root rot. 

This species develops a lignotuber and can regenerate by vegetative means from the lignotuber if the upper parts of the plant are destroyed by fire. It can also regenerate from seed.
