Detailed Botanical Description

Foliage & Growth Habit

The glossy, ovate leaves of Hydrangea arb. CB®Stand Up Pink’PBR NEW25 measure 5–15 cm in length and feature finely serrated margins. Spring foliage unfurls a bright green that matures to a deeper emerald by summer. In autumn, leaves may exhibit subtle bronzy highlights before dropping.

This cultivar exhibits a strongly upright and slightly mounding growth habit. Shoots develop in a robust, branching pattern, creating a dense framework that supports heavy flower heads. Growth averages 30–40 cm per year, filling out to a mature spread of approximately 100 cm.

Flowers & Blooming

Flowering occurs from early July through September. Large corymbs up to 20 cm wide open as pale rose and deepen to a richer pink tone over several weeks. Individual florets are sterile, contributing to the classic mophead appearance that hydrangeas are known for.

While not fragrant, the inflorescences serve as nectar sources for pollinators such as butterflies and honeybees. After the primary bloom, older flower heads can be left standing as winter interest or trimmed for a tidier appearance in spring.

Planting & Care Guide

Ideal Location

Select a site with morning sun and afternoon shade to prevent foliage burnout. In cooler climates, fuller sun exposure encourages prolific flowering. Ensure soil is amended with compost or well-rotted manure to improve fertility and drainage. Avoid sites with strong winds, which can desiccate flowers and foliage.

Watering

Keep soil evenly moist, especially during establishment and hot spells. Water deeply 1–2 times per week, allowing water to penetrate the root zone. Apply a layer of mulch 5–7 cm thick to conserve moisture and regulate soil temperature. During the growing season, feed with a balanced 10-10-10 slow-release fertilizer in early spring and again after the first flush of blooms to support vigorous growth and repeat flowering.

Pruning & Maintenance

Since this cultivar blooms on new wood, perform hard pruning in late winter or early spring. Cut back all stems to a pair of strong buds 30–45 cm above ground level to encourage vigorous growth and larger flower heads. Throughout summer, deadhead faded blooms to tidy appearance and, optionally, promote a second flush. Remove any dead or damaged wood as needed.
