Hydrangea arborescens 'Annabelle' (Smooth Hydrangea 'Annabelle') is a classic, easy-care flowering shrub prized for its oversized, rounded clusters of creamy white blooms. You get a bold summer display that brightens mixed borders, woodland edges, and foundation plantings, and the flower heads can be left on to add texture as they age.

Plant it where your site gives morning sun with afternoon shade, or full sun in cooler climates, and keep the soil evenly moist during establishment and summer heat. It adapts to many soils as long as drainage is reasonable; a layer of mulch helps hold moisture and keeps roots cool. Space plants so air can move through the canopy and allow room for the mature spread (about 48-72 in.).

Because it flowers on new wood, you can prune with confidence. In late winter or early spring, remove weak or crossing stems and, if you want a tidier shrub, cut stems back to a framework of healthy buds to encourage strong new growth. Support may help if heavy blooms weigh stems down, especially after rain.

Use 'Annabelle' to create a soft white backdrop for perennials, to anchor a shade-garden border, or to repeat along a path for a long, luminous summer look. Provide regular water during dry spells, and avoid letting the soil dry out completely while it is blooming.
