Originating from South America, Cassia (Senna pendula) was originally brought to Australia as an ornamental horticultural plant.
Local residents will recognise the weed from its bright yellow buttercup flowers which are currently in bloom. Cassia thrives in all conditions and can be found along the area’s beaches, creeks and roadsides.
Mayor, Joanna Gash said Cassia was an incredibly invasive weed, out competing many of the area’s native plants for nutrients and sunlight.
“While the flowers may appear quite alluring, make no mistake, Cassia is a serious environmental weed that needs to be eradicated from the Shoalhaven,” said Clr Gash.
“Many of the area’s 65 Bushcare Groups already spend countless hours controlling and removing this invasive plant from our bushland reserves, however more needs to be done.
“Council is calling on the local community to identify and remove any outbreaks of Cassia from within private property.”
“Small plants, under knee high, are able to be removed by simply pulling out the shrub from the roots while larger weeds may need to be sawn or cut at the base of the trunk and the stump painted with a small amount of undiluted Glyphosate.”
“Left unattended, Cassia will continue to reduce biodiversity in our natural bushland by outcompeting our native plants and creating an unwanted mono-culture.”
