Cornus controversa, or Giant Dogwood, is a striking ornamental tree, bringing elegance and unique beauty to gardens across USDA Zones 5 to 8. Native to regions such as China, Japan, and the Himalayas, this deciduous tree grows rapidly to an impressive 35 to 40 feet in both height and spread, with a distinctive horizontal branching pattern that creates a layered visual appeal. Known for its unusual alternate leaf arrangement—rare within the dogwood family—Giant Dogwood features simple, dark green leaves that transition to a variable, and sometimes striking, red-purple hue in fall.

Mid to late spring heralds the arrival of its creamy-white flowers, organized in showy flat clusters. These blooms yield bluish-black drupes in late summer, attracting a variety of birds and small mammals. Ideal for cool summer climates, Giant Dogwood thrives in acidic, moist, well-drained soils, appreciating some afternoon shade in hotter regions. Its resilience to twig blight and deer, along with its low maintenance, make it a perfect specimen or shade tree for large lawns and gardens. Whether enhancing a formal English garden, a children’s play area, or a tranquil city street, the giant dogwood offers both aesthetic grace and ecological value.
