This native viburnum offers ornamental interest throughout the seasons; flowers in spring, red fruit in late summer and red fall color. This American species (Viburnum opulus var. americanum; syn. Viburnum trilobum) is a better choice than the similar European cranberry-bush which has become an invasive plant in some areas.
