These European Snowball Viburnum (Sterile Viburnum) are loaded with bloom and ready to make a big impact right from the start. The lime-green clusters will soon turn pure white when fully open. These Planters’ Choice Grown plants will mature to about 12 x 10′ making them ideal for the back of the border or foundation. Hedging them also works well, just trim soon after bloom. The bright green leaves turn burgundy red in fall. No fruit on this sterile viburnum but sought-after nonetheless as a mature plant is a real stunner in full bloom!
