Arrowwood Viburnum 'Ralph Senior' AUTUMN JAZZ is a multi-stemmed deciduous shrub that earns its place in gardens through reliable beauty across multiple seasons. Typically reaching 6 to 10 feet tall with a similar spread, it produces showy white flowers in flat-topped clusters during late spring, followed by striking blue-black berries that birds find irresistible. Hardy in zones 3 to 8, this shrub thrives in full sun to partial shade and adapts well to clay soil and conditions near black walnut trees, making it especially valuable for challenging garden spots. The glossy, toothed leaves provide an attractive backdrop all season and develop variable fall color, completing a multi-season display with minimal fuss.

Late spring brings abundant white flowers in distinctive flat-topped clusters up to 4 inches wide, creating a clean, sophisticated look before the real show begins. Those flowers transform into glossy blue-black berries that persist into fall, drawing birds and butterflies in impressive numbers and adding visual interest long after bloom time fades. This shrub's ability to tolerate clay soil and thrive near black walnut trees makes it a solution for spots where many ornamentals struggle, while its low-maintenance nature means you enjoy the payoff without constant fussing.
This shrub excels as a hedging plant, where its upright, rounded form and dense multi-stemmed structure create effective screens and borders. Its showy flowers and ornamental fruit also make it valuable as a specimen shrub in mixed borders or naturalized landscapes where you want to encourage wildlife activity.

Prune immediately after flowering in June if shaping is desired. The naturally upright, rounded, multi-stemmed form requires minimal intervention in most settings, but pruning right after bloom allows the plant to set next year's flower buds without disruption.
