The Katsura Tree is native to Japan and China, where it grows as one of the largest hardwoods on the continent, capable of reaching 100 feet in the wild. In cultivation across zones 4 to 8, it settles into a more contained 40 to 60 feet, developing from a tightly pyramidal form in youth to something broader and more variable with age — low arching branches, shaggy bark on old trunks, and a presence that reads as genuine antiquity. The heart-shaped leaves emerge in spring as red-purple, mature through summer to blue-green, and then cycle through shades of apricot, gold, and orange in fall before dropping. As they decay on the ground, they release the scent of caramel or burnt sugar, a detail so specific and surprising that it changes the way a garden feels in October.

Plant this tree in full sun with moist, organically rich, well-drained soil, and shield it from strong winds and hot afternoon exposure, particularly while young. It demands consistent moisture during establishment and performs poorly in alkaline soils, where fall color becomes dull and foliage may scorch. The leaves bear a close resemblance to those of redbuds, though the two genera are unrelated — a useful confusion to know about when trying to identify young specimens. Katsura is a tree for large spaces: parks, golf courses, and open estates, or as a generous street tree where roots have room to develop without restriction.
