Preziosa Mountain Hydrangea

Preziosa Mountain Hydrangea (Hydrangea serrata 'Preziosa')

Preziosa Mountain Hydrangea (Hydrangea serrata 'Preziosa') is a refined and colorful lacecap hydrangea prized for its ever-changing blooms and richly tinted foliage. Compact and hardy, this cultivar delights with pink, mauve, or lavender flowers that shift in color throughout the season, often on the same plant. Its tidy size, exceptional fall color, and cold tolerance make it a versatile choice for foundation beds, borders, and woodland gardens where elegance and seasonal interest are desired.

Distinctive Features

'Preziosa' features delicate lacecap blooms that begin pale pink and gradually deepen to rose, purple, or violet as they age. Flower color is influenced by soil pH - more blue tones in acidic soils and pinkish hues in alkaline conditions. The rounded mophead-like flowers sit above burgundy-flushed green leaves that turn rich red and bronze in fall. This compact, rounded shrub typically matures at 3 to 4 feet tall and wide, making it ideal for smaller garden spaces and mixed borders.

Growing Conditions

• Sun Exposure: Partial shade preferred; tolerates morning sun with protection from intense afternoon heat.
• Soil: Moist, well-drained soil rich in organic matter; pH affects bloom color.
• Water: Moderate to high; requires consistent moisture for best flowering and foliage quality.
• Humidity: Performs well in humid and temperate climates; good airflow reduces fungal risk.
• USDA Hardiness Zones: 5-9; more cold-hardy than typical Hydrangea macrophylla types.

Ideal Uses

• Focal Point Plantings: Multi-toned blooms and rich foliage create a standout centerpiece.
• Foundation Beds: Neat habit and foliage color add four-season interest near buildings.
• Woodland Borders: Complements ferns, hostas, and shade-loving perennials in dappled light.
• Cut Flower Gardens: Blooms age beautifully and work well in both fresh and dried arrangements.
• Compact Mixed Borders: Fits well with dwarf evergreens, small flowering shrubs, and ornamental grasses.

Low Maintenance Care

Preziosa Mountain Hydrangea is easy to care for and thrives with consistent moisture and protection from harsh sun. It blooms on old wood, so pruning should be minimal to preserve next season's flowers.

• Watering: Maintain consistent moisture, especially during summer; mulch helps conserve water and insulate roots.
• Pruning: Prune only to remove dead or damaged wood after flowering; avoid aggressive trimming.
• Fertilizing: Feed with a balanced or hydrangea-specific fertilizer in spring; adjust soil pH to influence bloom color.
• Pest and Disease Resistance: Generally resistant to pests; ensure airflow to avoid powdery mildew or leaf spot.
• Winter Care: Mulch heavily in colder zones to protect flower buds and root zone.
