Brachychiton rupestris aka Queensland Bottle Tree

Brachychiton rupestris — commonly known as the Queensland Bottle Tree — is a striking, drought-tolerant tree native to Queensland, Australia. Named for its distinctive bulbous trunk that stores water, this tree can reach heights of 10–20 meters in its natural habitat. Its swollen base and sculptural form make it a popular choice for xeriscapes and modern landscapes. Slow-growing and resilient, Brachychiton rupestris thrives in full sun and well-drained soil, and it's often used both as a focal point in gardens and as a conversation-starting indoor bonsai specimen.
