Cranberry bush viburnum tolerates the poorly drained soils that characterize much of the Puget Sound lowlands. It handles seasonal flooding, poor drainage, and part shade. The maple-like leaves turn gold to burgundy in fall, and the translucent red berries persist into winter as bird food. The flat-topped white flower clusters in May-June include a ring of showy sterile flowers surrounding smaller fertile ones. The plant is documented as weedy in some regions, spreading by seed. In our climate, aphid pressure can be heavy, causing leaf curling that looks terrible but is rarely fatal. The compact cultivar 'Nanum' stays under 3 feet for border plantings. For a large shrub on a wet, poorly drained site, cranberry bush viburnum is one of the few plants that genuinely thrives rather than merely surviving.
