Plant of the month

November

Mahonia, Oregon Grape (Mahonia Aquifolium)

Mahonia

Mahonia is an evergreen shrub with holly like leaves that produces yellow racemes of fragrant flowers from November to March. Several species and varieties are available and in warm weather bees will work the flowers for nectar and pollen.

Large overgrown specimens can be cut back in early spring after flowering and will produce new growth that will flower the following autumn/winter.

October

Ivy (Hedera helix)

Bee on IvyIvy is an important source of nectar and pollen to honeybees at this time of year. Flowering late September to November and if warm enough flowers may still be found until late on in the year for bees to forage on. Pollen is consumed by workers in the autumn to enlarge the hypopharyngeal glands and fat bodies, allowing longer life of the winter bee.

Research has shown that honeybees going into winter with low levels of protein in their fat bodies have :

  • Shorter lives.
  • Are susceptible to Nosema and EFB.
  • Don’t winter well and the colony is likely to suffer from spring dwindling as nurse bees require protein to produce brood food.
