Diana Korean Spice Viburnum

Diana Korean Spice Viburnum (Viburnum carlesii 'Diana')

Diana Korean Spice Viburnum is a compact, fragrant spring bloomer that makes entry beds and foundation plantings feel more welcoming. It forms a dense, rounded shrub that looks finished even when it is not in flower. When the buds open, the scent carries beautifully and turns a simple walkway or patio into a place you want to linger. It is a smart choice when you want a refined shrub with strong seasonal payoff in a manageable size.

Distinctive Features

In early spring, deep pink to red buds open into rounded clusters of highly fragrant flowers that fade toward white as they mature. The bloom display is showy and classic, with a rich, spicy-sweet fragrance that stands out among spring shrubs. Dark green foliage provides a clean summer canopy and can develop red to burgundy tones in fall depending on conditions. Small fruit may follow, often starting red and ripening darker, adding subtle late-season interest.

Growing Conditions

• Sun: Full sun to part shade, with best flowering and density in full sun.
• Soil: Moist, well-drained soil is ideal, and it performs best where soil does not stay soggy.
• Water: Medium moisture, watering consistently to establish and during extended dry periods.
• USDA Zones: Zones 4 to 7.
• Mature Size: About 4 to 6 feet tall and about 4 to 6 feet wide.
• Habit: Compact, rounded, and dense.
• Bloom Season: Early spring.

Ideal Uses

• Focal Point: Plant near an entry, patio, or window where the spring fragrance and bloom clusters can be enjoyed up close.
• Foundation Planting: Use along broad walls where the rounded form adds structure and keeps beds looking full.
• Low Screening: Plant in small groups to create a dense privacy layer at a manageable height.
• Mixed Shrub Borders: Combine with evergreens and later-blooming shrubs for layered texture and season-long presence.
• Walkway Edging: Place where the shrub can soften hard lines without spilling into paths.
• Courtyard Gardens: Use in smaller spaces where a fragrant spring centerpiece elevates the whole planting.

Low Maintenance Care

• Pruning: Prune right after flowering if shaping is needed, since next season's blooms form on older wood.
• Watering: Water regularly the first growing season, then water deeply during drought to reduce stress.
• Mulching: Mulch to conserve moisture and moderate soil temperature, keeping mulch pulled back from the stems.
• Feeding: Feed lightly in spring only if growth is weak, since overly rich feeding can reduce flowering.
• Siting: Provide good air flow and well-drained soil to support long-term health.
