Mexican Fleabane could sometimes be confused with:


Found on old walls, cliffs, pavements and dry, rocky places, this is a slender perennial plant. It grows to 50 cm high, bearing spindly, daisy-like flowers (13–16 mm) in inflorescences on slender, leafy stems from July to September. The white ray florets are narrow and frequently turn pink as they age; these encircle a yellow cushion of disc florets. The lower leaves are toothed whereas the narrow, upper leaves are entire. Originally from Mexico, this plant was introduced into gardens in the mid-nineteenth century and has now established itself in several locations. It is a member of the Asteraceae family.

I first recorded this plant near Shankill, County Dublin in 1978 and photographed it in Dalkey, County Dublin in 2010.
