Arrowwood Viburnum

Use Arrowwood Viburnum to build a loose hedge, a tall boundary planting, or a backdrop for lower perennials and shrubs. Its upright, rounded, multi-stem habit reads best in a broad bed or along a property edge, rather than squeezed beside a narrow walk. Keep the planting line far enough from paths, gates, and walls that its mature branches will not crowd circulation. It can also anchor a native or wildlife-focused border, with open foreground space left for plants that remain below its canopy.^[1]

Plant individual shrubs 7 feet apart, center to center, for a linked hedge or mass that can knit together over time. Each plant may ultimately occupy about an 8-foot-wide footprint, so reserve depth as well as length when drawing the bed. For a less continuous screen, allow wider gaps and retain access from one side for pruning and cleanup. Avoid placing large shrubs directly in front of it, where they would compete for the same mature space.

Give this shrub a full-sun position and moderate water. A site with average, moist, well-drained soil supports its long-term use in a hedge or mixed border. Place it where irrigation can reach the entire root zone during dry stretches, especially while the planting is establishing, but do not make it the low point of a bed that stays waterlogged.^[1]

White flower clusters arrive in late spring to early summer, then give way to blue-black fruit later in the season. Because Arrowwood Viburnum is deciduous, its winter outline will be more open than a year-round evergreen screen. Prune only as needed immediately after flowering; later pruning can remove the developing fruit display.^[1][2]
