Giant Dogwood is a striking deciduous tree that commands attention with its distinctive horizontal branching arranged in tiers, a branching pattern so unusual among dogwoods that only one other species shares it. Growing 35 to 40 feet tall (occasionally reaching 60 feet) with equal spread, this rounded tree thrives in hardiness zones 5 through 8, making it accessible to gardeners across much of the temperate United States. In late spring, small creamy-white flowers cluster in flattened groups up to 3 to 7 inches wide, transforming the entire canopy into a showy display despite the individual flowers being quite small. What truly sets this species apart is its alternate leaf arrangement, a rarity among dogwoods, combined with its rapid growth and low-maintenance character.

The tiered, horizontal branching pattern creates an architectural silhouette that remains striking even in winter, while the abundance of small white flowers in May and June attracts both butterflies and birds. This tree demonstrates genuine deer resistance, a quality many ornamental trees lack, and it thrives in cool-summer climates with moderate moisture and good drainage. Unlike its close relative Cornus alternifolia, Giant Dogwood shows resistance to twig blight, making it a more robust choice for gardeners managing disease pressure.
Giant Dogwood serves as an exceptional flowering tree for landscapes where its tiered branching architecture and seasonal floral display provide year-round visual interest. It attracts pollinators and birds, making it valuable for wildlife-focused garden designs and native plantings where ecological benefits matter as much as ornamental appeal.

Minimal pruning is required, though you can selectively remove lower branches to emphasize the distinctive tiered horizontal branching habit if desired. Remove any dead, diseased, or crossing branches to maintain structure and improve air circulation. Prune in late winter or early spring before new growth emerges.
