About Macadamia nut
Macadamia integrifolia, known as Queensland Nut, is an evergreen tree native to Australia, renowned for its delicious macadamia nuts. It features glossy dark green foliage and can grow quite tall, making it ideal as an ornamental tree in large gardens or subtropical orchards. Its white or pink flowers, arranged in pendulous racemes, add extra appeal before the fruit develops.
Native range

Care tips
It requires full sun and well-drained, slightly acidic to neutral soil, enriched with organic matter. Watering should be regular, especially during dry periods and fruit formation, avoiding waterlogging which can lead to root rot. Protect the plant from frost, as it is sensitive to low temperatures, and avoid heavy, clayey soils that hinder drainage.
