Almost as showy as hydrangeas (but far hardier), the “snowball” viburnums are in full bloom right now. Viburnum opulus ‘Roseum’ (syn. ‘Sterile’) is closely related to Viburnum trilobum, which is commonly known as high bush cranberry or American cranberrybush, despite the fact that it is not really a cranberry at all. (Viburnums are from the honeysuckle family, while “bog” cranberries are related to plants such as bilberries, blueberries, and heather). Viburnum trilobum grows here in Alberta as well, and bears bright red fruit with a tart taste reminiscent of true cranberries. The snowball viburnums do not bear fruit, but the ornamental value of their gorgeous blossoms is obvious.
Do you grow any types of Viburnums in your garden? Have you ever eaten high bush cranberry fruit?
The blooms of snowball Viburnum are initially a gorgeous acid-green colour…
…and mature to a creamy white.
