The yellow daisy of Fireweed (Senecio madagascariensis) is flowering now. So please keep an eye out for this weed that threatens to break out in teh Canberra Area. The 'daisy-like' flower-heads (15-20 mm across) have 12-15 yellow 'petals' (i.e. ray florets) that are 6-14 mm long. They have a yellow centre made up of numerous tiny flowers (i.e. tubular or disc florets) and are surrounded by about twenty (19-21) greenish bracts (4-5 mm long). These flower-heads (i.e. capitula) are loosely clustered at the tips of the branches.
