Viburnums are summer-green, sometimes evergreen bushes. A common viburnum (Viburnum opulus) is growing - till 4 m high and wide bush in wildlife in Latvia. It is a moisture demanding plant, growing well in vet and organic matter–rich soils. The first three varieties - 'Ventvort', 'Has', 'Endrew' - were divided by American gardener H. Morgan from three lobes viburnum (Viburnum trilobum).
