About this weed
This widespread agricultural crop was photographed at Herdsman Lake growing in damp soil conditions. It was originally introduced as an agricultural crop and the bright yellow flowers can be seen across the Wheatbelt of Western Australia in spring. It may have originated as a hybrid of B. oleracea and B. rapa.
Description
Canola is an annual or biennial herb growing to 1.5 m in height. The leaves are blue-green and those at the base may be bristly. It is common to see plants growing along country road verges where it may have been spilt from trucks.
Impact on Bushland
Unfortunately this agricultural crop has escaped the paddocks and can now be seen in bushlands and wetlands in various parts of the South-West.
Location
Mainly growing on roadsides in the Wheatbelt but has been seen as far away as the Pilbara.
