Blooms for Bees


Blooms for Bees is a citizen science project to promote and improve gardening for bumblebees.

Bumblebees are popular and important pollinators. There are currently 25 species of bumblebee in the UK. Unfortunately, UK bumblebee populations have declined in recent years, with two species becoming extinct since 1940. This is largely a result of the intensification of agricultural practices, which has reduced the availability of the flowers that bumblebees feed on.

Gardens and allotments offer an amazing opportunity to create vibrant flower rich habitats to support these vital pollinators. Despite this, little is known about which bumblebee species visit gardens and allotments, or which flowers are the most important sources of nectar and pollen.

Between 2017 and 2020, a total of 1,500 participants conducted over 2,800 flower surveys and submitted their data to the Blooms for Bees project.

A total of 5,263 bumblebees were reported, and we were able to confirm that 15 of the UK’s 25 bumblebee species were visiting gardens and allotments. This included the seven most common species, as well as the scarce Ruderal Bumblebee, Moss Carder Bee, Heath Bumblebee and Bilberry Bumblebee.

A range of flowering plants were surveyed, and Allium, Dahlia and Origanum all emerged as valuable for supporting a wide range of UK bumblebee species and would be good choices for containers and smaller gardens. We also found that Dahlia x hortensis Mignon Series was as a good alternative to annual bedding plants.

We are currently working on funding applications to further develop the project and enable updates to improve the Blooms for Bees app.
