The Philadelphia Fleabane (Erigeron philadelphicus L.) is one of our
interesting spring plants and will repay careful study. The leaves of
the stem in most individuals have a decided polarity and for the most
part are twisted so as to stand in a single plane. In this respect the
plant is as striking as any of the so-called compass plants, although
the plane in which the leaves lie may be in any direction. Another
interesting adaptation is the drooping of the top of the young plant.
The entire inflorescence nods at first and finally the individual heads,
but one by one these assume the upright position as the flowers begin to
open.
