Preferred flowers

Most double flowers are of little use, because they're too elaborate. Some are bred without male and female parts, while others have so many petals bees can't get to the nectar and pollen to collect it. This is the main reason why single dahlias are popular with many bees, while doubles are usually ignored.

The single-flowered rose family, which includes crab apple, hawthorn and potentilla, seem to be irresistible to our buzzing friends, as are the flowers of fennel, angelica and cow parsley, and sedums.

Tubular-shaped flowers, such as foxgloves, snapdragons, penstemons and heathers, are also all-favourite feeding places for bees.

Plants for life

It's vital you provide flowers throughout the bumblebee's life-cycle, from March to September. It's also a good idea to have at least two nectar- or pollen-rich plants in flower at any one time during this period. The nectar feeds the adult bee, while the pollen is collected to feed the young. Of course, the more flowers you have, the more attractive your garden is to bees, so you can never have too many!
