Capeweed (Arctotheca calendula) is identified as a priority weed for the southern region. Capeweed affects a wide variety of land managers, from suburban gardeners through commercial farmers.
In the home garden it competes with herbaceous and lawn plants. Capeweed is also an economically significant competitor of crops, grass and clover, and may be the dominant plant in some pastures. Conversely, this weed is nutritious to stock, for which it is valued by some graziers.
Capeweed is an annual herb, germinating in Autumn, growing as a rosette through Winter and flowering in late Spring to Early summer, before dying off.
Rosettes look similar to many other flat weeds, but can be distinguished by the hairy, very pale undersides of the leaves. Flowers are pale yellow daisy flowers with a black centre and are highly visible in southern Tasmania this month.
Capeweed is most efficiently controlled in Autumn. Plan now for Capeweed control after February 2008. Nonetheless there are some effective control options available to land managers at this time of year.
