Formerly Aster puniceus. These common blue asters like slopes above streams and squishy wet ground. These grew on the bank of a brook near Wexford. They are quite variable: Britton & Brown say that “races differ in pubescence, leaf-form, and leaf-serration,” meaning that anything you say about the shape of the leaves or how rough or hairy they are has to be followed by the words “or not.” The leaves of these plants were rough and sandpapery, and the stem quite hairy. The name puniceum, or Punic (“having to do with Phoenicia”), was doubtless suggested by the deep Tyrian-purple color of the stems.
