Notes
Flowers May to June
Wetland indicator: FACU
One of the more attractive members of this genus and blooming a little earlier than similar species, i.e. in spring which may be why it is called robin's plantain. Like E. philadelphicus it has cauline leaves that clasp the stem but has fewer and larger heads with fewer rays (50-100 vs. 150-400) that are wider (mostly 1+ mm vs. less than 1 mm).
