Cluster fig
Ficus racemosa
The cluster fig, also called the red river fig, udumbara or gular, is a large, fast-growing fig tree of riverbanks and moist lowland forest, native from Pakistan and India through Southeast Asia and southern China to New Guinea and northern Australia. Its figs grow in dense clusters straight from the trunk and older branches and ripen reddish orange to dark crimson, and they are eaten across its range, raw, cooked, pickled or preserved. Wikipedia notes that the tree is important in Hinduism and Buddhism and is often planted in temple grounds and villages. It is a tree for frost-free gardens with room to spare: Plants For A Future gives 39 feet tall and wide and Flora of China up to 82 to 98 feet, and Plants For A Future rates it for USDA zones 9 to 12 while calling it hardy only to UK zone 10, so treat zone 9 as marginal. Like other figs, its milky sap irritates skin and should not be eaten, so wear gloves when pruning.
