Please note, due to incredibly high demand, we are currently only able to accept registrations from RHS Affiliated Societies.

If you are interested in participating in Blooms for Bees, but are not an RHS Affiliated Society, you will still be able to use the Blooms for Bees app to survey any flowering plant in your garden or allotment from the 1st April 2017.

RHS Affiliated Societies can register for dahlia trial packs by following the instructions below.


About the dahlia trial

Many traditional bedding plants have been bred for appearance, often to the detriment of their value to pollinating insects. The Blooms for Bees team is interested in improving bedding plant recommendations to support pollinators.

We are looking for citizen scientists to take part in an experiment to assess the Mignon Series of dahlias, to determine which bumblebees they are popular with and whether the various colours differ in their attractiveness to bumblebees.

Dahlia trial participants will be provided with seed for purple, red and white dahlias, and asked to grow three plants of each colour. Participants will need to monitor the flowers in each colour group for 5 minutes, at least once a month, and take a photograph of each visiting bumblebee.

Participants will be able to report observations using the free Blooms for Bees app (available on Android and iOS smartphones/tablets from April 2017). Those without a smartphone/tablet will be able to submit photographs through the Blooms for Bees website.

This experiment is part of the Blooms for Bees project, which is funded by the Heritage Lottery Fund, and is a partnership between Coventry University, Garden Organic, the Royal Horticultural Society and Bumblebee Conservation Trust.
