One of several fleabanes in our area, this species is also known as
daisy fleabane and rough fleabane. Both names are also used for other
flowers. Fleabanes are typified by many ray petals, and relatively broad
disks. The two most common other fleabanes in our area are Common
Fleabane (E. philadeplhicus) and Annual (also called Daisy) Fleabane
(E. annuus). Common fleabane has many more rays, typically 150-400.
Annual fleabane is similar, distinguished by somewhat more (80-120) rays
that tend to be longer than the disk diameter, and more sharply toothed and
The name fleabane refers to an old belief, which does not seem to be true,
that the plants would repel fleas.
