Oilseed rape : Brassica Napus

Plant : Oilseed rape has become a key feature of the beekeeping calendar and landscape in rural Northumberland.  It is mostly autumn sown in the region, flowering early in the spring.  It is a member of the Brasicaceae family and honey bees will travel 2 km or more for its nectar and pollen.  Although it is grown as a commercial crop it is common as a weed on roadsides and arable land.  The stems reach a height of  over 100 cm, with bright yellow flowers appearing on the top sections.

Flower : The flower has four petals, which form the regular crucifix arrangement typical of the family and it flowers between March and June.
