Deciduous & Flowering Shrubs

Limelight panicle hydrangea

Hydrangea paniculata 'Limelight'

‘Limelight’ is an upright, deciduous panicle hydrangea with large flower clusters that open pale green in summer, turn creamy white, and age pink toward fall. At maturity, expect a shrub about 6 to 8 feet tall and wide; allow that space when placing it along a hedge or near a path. Its flowers can also be cut fresh or dried. Choose full sun to partial shade, with reliable moisture in sunnier spots. Moist, well-drained soil suits it, while persistent winter sogginess can trouble the roots. Prune in late winter or early spring, before new growth carries the season’s large flowers.

Southwest Washington gardens

Give it a good start.

In Southwest Washington, choose a site that drains through wet winters and water during dry summer periods. Avoid spots where heat reflects onto the leaves.

Soil, drainage & water

Plant in moist, well-drained soil. Water during dry periods, especially in sunny sites, and avoid ground that stays soggy.

A little care goes a long way

Growing well, season after season.

Prune in late winter or early spring, before new growth develops. Flowers form on current-season growth, so heavy summer pruning can reduce the display.
