Flowering shrubs give gardens and landscapes structure and elegance—and Snowball Viburnum is sure to impress with its snowy white flowerheads in early summer. Growing 6-10 ft. tall with a similar spread, this shrub has a rounded, vase-shaped habit, making it ideal for a flowering hedge or privacy screen along property borders. Its dark green, ovate leaves provide a nice backdrop for perennial beds. The non-fragrant flowers emerge lime green and quickly turn white. They attract butterflies too! A native to China, Snowball Viburnum is deciduous in northern zones and semi-evergreen in warmer climates. It grows best in well-drained, acidic, loamy soil. Plant in full sun to partial shade. Zones 6-9.
