A large, fast-growing California native tree with attractive exfoliating bark that reveals pale inner wood. It thrives in full sun and is drought-tolerant once established, making it ideal for riparian areas and large landscapes.

Why grow it

Western sycamore grows substantially faster than its eastern counterpart (Platanus occidentalis) and tolerates drier conditions, making it better suited to western landscapes with limited water. Among native California riparian trees, it offers superior drought tolerance once established while providing reliable summer shade and structural presence in large-scale designs. Its exfoliating bark provides winter interest without requiring supplemental irrigation in appropriate climates.

Watch out for

This tree produces considerable leaf and twig litter throughout the year, requiring regular cleanup in manicured settings. The aggressive root system can damage nearby hardscape or underground utilities if planted in confined spaces, so site selection should account for eventual mature spread.
