Many people incorrectly call this weed Cape daisy. It usually has a capital “C” as is named after the Cape Province in South Africa from where it originated. It can be differentiated from many of the other rosette weeds found in turf by the quite jagged, angular lobes, which aren’t as rounded as many of the closely related dandelion-type flat-weeds. (Massey Uni Weeds Database).
A young rosette found growing on a grass verge. No sign yet of its yellow daisy-like blooms.
