HYDRANGEA PETIOLARIS (NL)

Introduction to Hydrangea petiolaris

Hydrangea petiolaris, commonly known as Climbing Hydrangea, is a vigorous, self-clinging deciduous climber that brings elegance and charm to shaded walls, fences, and tree trunks. Known for its lush green foliage, creamy white lace-cap flowers, and exfoliating bark, it is a standout choice for gardeners looking to soften hard surfaces or add vertical interest.

Key Features:

• Botanical name: Hydrangea anomala subsp. petiolaris

• Common name: Climbing Hydrangea

• Height and spread: Up to 10–15 metres high and 5 metres wide over time

• Growth rate: Moderate to fast

• Flowering period: Early summer (May–July)

• Foliage: Mid-green, heart-shaped leaves that turn yellow in autumn

• Climbing method: Aerial roots (self-clinging, no need for support wires)

Planting Conditions and Positioning

Hydrangea petiolaris is ideal for challenging spots in the garden, such as north or east-facing walls where other plants may struggle to thrive. With the right conditions, it will reward gardeners with dense foliage and a beautiful floral display.

Site and Soil:

• Prefers moist, well-drained soil with plenty of organic matter.

• Tolerates a range of soil types including clay, loam, and sandy soils.

• Performs best in slightly acidic to neutral soil pH.

• Thrives in part shade to full shade, making it ideal for darker garden spots.

• Will tolerate some sun if soil remains consistently moist.

Planting Tips:

• Plant in early spring or autumn for best results.

• Ensure adequate spacing from walls or structures to allow root development.

• Add compost or well-rotted manure when planting.

• Water thoroughly after planting and keep well-watered during the first growing season.

Good To Know:

• This climber can take a few years to establish before vigorous growth begins – patience is key.

• Once established, it becomes a low-maintenance plant with long-term appeal.

Care, Maintenance and Seasonal Tips

Hydrangea petiolaris is relatively easy to care for once established, but a little attention will ensure it remains healthy and attractive throughout the year.

Watering:

• Keep soil moist, especially during hot, dry spells in summer.

• Water thoroughly during prolonged dry periods and when in containers.

Feeding:

• Apply a slow-release balanced fertiliser in early spring.

• Mulch annually with organic matter such as bark, compost, or leaf mould to retain moisture and improve soil structure.

Pruning and Training:

• Minimal pruning is needed.

• Remove dead or damaged wood in late winter or early spring.

• To control size, lightly prune after flowering, but avoid cutting into old wood as it may reduce next season’s blooms.

• Can be trained along trellises, walls, or tree trunks—simply guide young stems in the desired direction.

Winter Hardiness and Other Notes:

• Fully hardy in the UK and Ireland.

• Deciduous: will lose leaves in winter, revealing attractive, peeling bark.

• Excellent for wildlife gardens—flowers attract pollinators like bees and butterflies.

• Can be grown in large containers, though performance may be reduced compared to those grown in open ground.
