Exploring the World of Viburnum Shrubs
Are you looking to enhance your yard with a beautiful, low-maintenance white-flowering shrub? Look no further than the viburnum bush! With over 200 species in the Viburnaceae family, there is a wide variety of viburnums to choose from. These trees and shrubs are grown in temperate regions and are known for their showy displays of white (sometimes pink-tinted) flowers in clusters called corymbs. Most viburnum species are dioecious, meaning they require cross-pollination with another variety or species to produce fruit, while a few are monoecious. If both male and female flowers are present, the female flowers later produce drupes in various shades of red, purple, blue, or black.
In this comprehensive guide, we’ll explore 12 popular species of viburnum that are sure to add beauty and charm to your landscape. Before we dive into the specific species, it’s important to note that while some viburnum bushes have edible berries, others produce berries that are mildly toxic to humans and animals if ingested in large quantities.
