About Agathis robusta
About Agathis robusta
Agathis robusta, or Queensland Kauri, is a tall, long-lived conifer native to Queensland’s subtropical rainforests. Known for its straight trunk, symmetrical shape, and dark green, glossy foliage, it’s a stately tree well suited to larger landscapes, parks, and feature planting in open areas.
Typically growing up to 30–40 metres in ideal conditions, but more commonly 15–25 metres in cultivation, it develops a strong central leader and clean trunk, making it useful in formal planting schemes or as a large shade tree.
They look excellent when planted as a feature in lawns, as avenue trees in large-scale plantings, or allowed to stand alone in open spaces where their clean form can shine. Agathis robusta performs best in full sun with well-drained soil and benefits from protection during early establishment. Low maintenance once settled, and tolerant of a wide range of climates outside of extreme cold.
