Queensland Bottle Tree with Iconic Swollen Trunk
Brachychiton rupestris, commonly known as the Queensland Bottle Tree, is a striking Australian species recognized for its distinctive swollen trunk that gradually forms a bottle‑shaped silhouette. This unique form allows the tree to store water, making it exceptionally drought tolerant and well suited to arid and Mediterranean landscapes. Its smooth grey bark, soft green foliage, and sculptural presence make it a standout specimen in both residential and large‑scale plantings.
Perfectly suited to warm climates, dry gardens, and water‑wise landscapes, Brachychiton rupestris thrives in full sun and well‑drained soils. Its slow, steady growth and long lifespan make it ideal for feature planting, avenue plantings, and architectural landscape designs where its iconic trunk can be showcased.
