|'Roseum' is the European Snowball or Guilder-rose that has barren flowers which are extremely. The flowers in a apple green in early stages, change to white and cover the shrub in mid-May. This shrub is an old favorite around older residences. Aphids infest this form quite heavily and often distort the young leaves and stems.
Viburnum opulus is spreading shrub with arching branches, growing 8 to 15 feet high. The foliage is glossy dark green, sometimes turns yellow-red to purple in fall, though not consistently. The white flowers bloom in late spring, on flat topped cymes, with sterile showy flowers combined with inconspicuous fertile flowers. A red berry-like drupe ripens in the fall, quite ornamental, gradually shriveling over the winter.
Easy to grow, adaptable to different soil types, occasionally bothered by aphids and borers. Good multipurpose shrub.
