Hydrangea macrophylla 'Weidner's Blue'

Lacecap Hydrangea

Hydrangea macrophylla ‘Weidner’s Blue’ is a deciduous shrub valued for its large mophead flower clusters in strong blue tones when grown in acidic soil. This bigleaf hydrangea blooms in summer on old wood, producing full rounded flower heads that may shift toward pink-lavender in less acidic soils. Its dark green foliage and dense flowering habit give it a bold traditional hydrangea appearance.

Type: Deciduous shrub
Mature Size: Width: 4–6 ft · Height: 4–6 ft
USDA Zones: 6a–9b

Form: Rounded, upright

Light: Part shade to morning sun

Soil: Rich, moist, well-drained soil; acidic soil maintains strongest blue color

Features & Landscape Uses:
An excellent choice for foundation plantings, borders, woodland gardens, and mixed shrub beds where strong blue summer color is desired. The blooms are also useful for fresh or dried arrangements.

Care:
Plant in part shade with fertile, organic-rich soil that remains evenly moist. Prune only after flowering since buds form on old wood. Maintain acidic soil conditions for best blue flower color and mulch roots to conserve moisture.
