Origin
The Brachychiton rupestris is a tree species native to eastern Australia, mainly Queensland. It grows there in dry forests and savannah-like areas. The tree belongs to the Malvaceae family. This species is adapted to seasonal drought and has evolved in a climate with distinct wet and dry periods.

Characteristics
Brachychiton rupestris is distinguished by its strikingly swollen trunk, which stores water and makes the tree resistant to drought. The trunk is grey-brown in colour and can become several metres thick. The leaves are usually palmate and deeply lobed, changing in shape as the tree matures. During the growing season, the tree produces creamy white to yellow flowers in loose clusters, which often appear before the new leaves develop. In the wild, the tree can reach a height of 10 to 25 metres.

Care
Brachychiton rupestris requires a sunny position and grows best in well-draining soil. This tree tolerates low temperatures down to just below freezing, but it is not fully hardy. Moderate watering is sufficient, as the species is naturally drought-tolerant. Overwatering should be avoided, as this can lead to root rot. The tree has little need for extra fertilisation.
