A slow-growing and drought tolerant tree, it can live for 500 years. Seed production is cyclic, with a year of high production being followed by 2 - 3 years of lower yields. The tree flowers on new growth produced in spring, the seed ripening in its first year. Intolerant of root disturbance, trees should be planted in their permanent positions whilst young. Hybridizes freely with other members of the genus.Plants in this genus are notably resistant to honey fungus.
