Plant Profile: Mexican Daisy/Fleabane (Erigeron karvinskianus )

Mexican daisy is a tender herbaceous perennial native to Mexico, Central America, and parts of South America but has naturalized in elsewhere including the west coast of the US. It is a member of the aster family, Asteraceae, that also includes true daisies, goldenrod, and lettuce. Growing  from a woody rhizome the plant is trailing with a highly branched, wiry stem. The linear to oval leaves are slightly hairy, one inch long, and may be tipped with several teeth. The ¾” wide flowerheads have yellow disc flowers surrounded by white ray flowers that fade to pink at the end of a long bloom time. Plants readily colonize in cracks and crevices of paving or stone walls where they add color from late spring into fall.
