Japanese Pagoda Tree (Scholar Tree)
Styphnolobium japonicum
A tough urban shade tree, one of the few large trees flowering in summer with big creamy panicles, followed by knobby bean pods. Highly tolerant of heat, drought, pollution, and poor soils, it is a reliable city and street tree; young trees are gangly and need structural pruning to develop good form.

Common questions
Why is it valued as a city tree?
Japanese pagoda tree shrugs off heat, drought, air pollution, and compacted urban soils better than most large shade trees, and it adds rare summer flowers, making it a dependable street and plaza tree.
Why does my young pagoda tree look awkward and floppy?
Young trees are notoriously gangly with weak, crossing branches, but they develop into a handsome rounded canopy. Early structural pruning to a strong leader and well-spaced scaffolds is well worth it.
