Bumblebees are vitally important for pollinating hundreds of plant species, including many crops. But they are under threat from the loss and degradation of our habitats due to pressures such as development, agricultural intensification and climate change. There are 24 species in the UK.

Bumblebees look for certain types of flowers. Those with shorter tongues need short, open flowers, with nectar within easy reach. This includes flowers from the daisy family and alliums, which have a number of small flowers on one stalk. This type of flower offers a small reward for each probe, but those bumblebees with long tongues can enjoy deeper flowers like honeysuckle, which have significantly more nectar per flower. 

Some bee species have even resorted to ‘robbing’ nectar by cutting a hole in the base of the flower and getting to it that way! The flower loses out because this means its pollen is not transported to other flowers nearby.

Having some early and some late flowers in your planting mix will prolong the nectar season for bumblebees

 

Some bumblebee flower favourites

• The buff-tailed bumblebee and white-tailed bumblebee prefer short, open flowers, such as white clover and comfrey. Both are hole-biting, ‘nectar robbers’. The buff-tailed bumblebee rarely visits pendulous flowers as its large size means it is not agile enough to do so.
• The garden bumblebee has a long tongue, so it can visit flowers with petals that form long tubes, such as honeysuckle, delphiniums and catmint.
• The red-tailed bumblebee is a large bee that likes to land on flowers with ‘platforms’, such as daisies and knapweeds.
• The early bumblebee is a small, agile bee, with a medium-length tongue, which means it can probe a range of flower depths and is able to visit upside-down and drooping flowers, such as comfrey and viper’s-bugloss.
• The common carder bee is long-tongued and able to get nectar from long-tubed flowers, such as the late flowers of white dead-nettle. Male bees seem to visit compound daisy-like flowers, such as marsh thistle, more than females.

Seasonal planting

Having some early and some late flowers in your planting mix will prolong the nectar season for bumble bees and other pollinators, too. Planting them in drifts will help bees to recognise them easily, allowing them to visit repeatedly.
