Dahlias from the Mignon Series produce single (not double), pollen and nectar-rich flowers which are thought to be visited by many pollinators. We have designed a simple trial to determine which bumblebees Mignon Series dahlias are popular with and whether bumblebees demonstrate a colour preference within the Series.
We are grateful to the 2,200 participants from across the UK, who are growing and monitoring white, red and purple Mignon dahlias in summer 2017. In addition to these surveys, we are measuring the amount of nectar and pollen produced by Mignon Series dahlias, and exploring whether this varies between the colour forms in the Series.
