Cornus controversa is native to China, Japan, Korea, the Himalayas, and Vietnam, and in maturity it becomes a genuinely imposing tree. Its defining feature is architectural: horizontal branches arranged in distinct, spreading layers that give it an almost constructed quality — elegant and picturesque in equal measure. Creamy-white flowers appear in late spring to early summer in flat-topped clusters across each tier, followed by small bluish-black drupes that attract birds and small mammals through late summer. The simple leaves are dark green above and silvery-green beneath, and the cultivar 'Variegata' adds creamy-white leaf margins to the layered form.

At 35 to 45 feet tall, this is a tree that needs space and a long view to be properly appreciated. It prefers acidic, moist, well-drained soil and performs best in cool summer climates; some shade in hot regions prolongs its health. Growth is moderate to rapid, and pruning to lift the canopy will be needed as the tree matures to provide clearance beneath. The alternate leaf arrangement — found in only one other dogwood, the native Cornus alternifolia — gives this tree its species name, a nod to the botanical debate its unusual morphology once provoked.
