Is Viburnum opulus 'Roseum' attractive to bees and other pollinators?
This cultivar has gorgeous, but sterile flowers, so I am puzzled if it produces nectar or pollen at all, which would make it desirable for bees.
There is a blog post that claims that some plants with sterile flowers are attractive to bees (their flowers produce nectar, but not seed). The plants mentioned are:
- Geranium rozanne
- Helenium ‘Sahins early flower’
- Lavundula ‘Eidelweis’
- Agastache ‘Blue boa’
- Erysimum ‘Bowles mauve’
But Viburnum opulus 'Roseum' is not among them. (It may be not considered in the study altogether.)
