Starlight Dogwood

Starlight Dogwood (Cornus kousa x nuttallii 'KN4-43')

Starlight Dogwood is a vigorous hybrid flowering dogwood valued for its large creamy white bracts, upright form, and strong disease resistance. Its late spring bloom display can cover the tree heavily, bringing bright seasonal color after many earlier flowering trees have started to fade. Deep green foliage gives the tree a healthy summer appearance before turning attractive red tones in fall. With its refined oval habit, manageable size, and durable landscape performance, Starlight Dogwood is a strong choice for front yards, specimen plantings, mixed borders, and open lawn areas.

Distinctive Features

Starlight Dogwood produces large, firm, creamy white to slightly greenish white bracts in late spring, often creating a profuse floral display across the branches. This hybrid combines Cornus kousa and Cornus nuttallii parentage, giving it the upright form associated with Pacific dogwood and the disease resistance associated with kousa dogwood. The tree develops a dense, upright oval canopy with deep green foliage through summer and red fall color as the season changes. Sparse red-orange to strawberry-like fruit may appear in fall, adding seasonal interest without becoming a major cleanup concern.

Growing Conditions

• Sun: Grows best in full sun to partial shade, with some afternoon shade helpful in hot or exposed locations.
• Soil: Prefers fertile, acidic, well-drained soil with good organic matter and steady root-zone moisture.
• Water: Performs best with medium, even moisture during establishment and shows some tolerance of drier conditions once established.
• USDA Zones: Hardy in USDA Zones 6 to 8, with best performance in well-sited landscapes that avoid extreme heat or drought stress.
• Mature Size: Typically reaches about 25 to 30 feet tall and 15 to 25 feet wide with age.
• Habit: Forms a vigorous deciduous ornamental tree with a dense upright oval habit and refined branching structure.

Ideal Uses

• Focal Point: Use as a white-flowering focal point in front yards, entry gardens, open lawn areas, or courtyards where its heavy spring bloom display can stand out.
• Specimen Tree: Plant as a standalone ornamental tree where its flowers, upright form, fall color, and seasonal fruit can be appreciated from multiple angles.
• Mixed Border: Add to large shrub and perennial borders for height, late spring flowers, summer structure, and fall color.
• Woodland Edge: Use along lightly shaded woodland margins where it can receive filtered light, steady moisture, and room to develop naturally.
• Residential Landscape: Plant where a refined small to medium ornamental tree is needed for seasonal color without the scale of a large shade tree.

Low Maintenance Care

• Watering: Water deeply during the first few seasons and during extended dry periods to keep the root zone evenly moist but not saturated.
• Mulching: Apply a broad mulch ring to conserve moisture, moderate soil temperature, and reduce competition from turfgrass.
• Pruning: Prune lightly during dormancy or after flowering to remove dead, damaged, crossing, or crowded branches while preserving the upright oval form.
• Fertilizing: Fertilize only when needed based on soil conditions, avoiding excessive nitrogen that can push weak or overly soft growth.
• Deer Protection: Protect young trees from browsing and trunk rubbing in landscapes with moderate to heavy deer pressure.
• Site Care: Provide good air circulation, avoid planting too deeply, and keep mulch pulled away from the trunk to support long-term health.
