Brachychiton rupestris, the Queensland Bottle Tree, is one of the most distinctive trees in cultivation, instantly recognised by its dramatically swollen bottle-shaped trunk. The trunk stores water, giving the tree exceptional drought tolerance and a bold sculptural presence.
Bottle Tree grows slowly to 10-15 metres tall and 5-8 metres wide, with the characteristic trunk swelling developing gradually over many years. The narrow deep green leaves and upright open canopy contrast beautifully with the broad trunk, suiting feature positions in dry-climate gardens, civic landscapes, and rural properties.
Bottle Tree is extremely drought tolerant once established and thrives across QLD, NSW, VIC and SA in full sun with well-drained soil. Its non-aggressive habit makes it safe to use near paving and structures. Clusters of yellow-green bell-shaped flowers appear in early summer.
