Also known as Pilosella aurantiaca, this is one of our most spectacular weeds. If you draw a line right across the middle of Pennsylvania from east to west, you will mark the southern border of the range where Orange Hawkweed is common. There are, however, isolated stations in the city of Pittsburgh, one of which is St. Peter’s Cemetery in Arlington, where these pictures were taken on June 3.
We often picture the flowers, but the seedheads of the common dandelion are at least as decorative and probably more artistic.
It’s the middle of April, and cheery yellow dandelions are everywhere. We always have room for more pictures of them.
Coltsfoot is one of our earlier spring flowers. It likes the edge of the woods, but it can sprout almost anywhere; these plants were growing at the edge of a parking lot in Banksville. The blooming stalks come straight out of the ground before any leaves appear.
Coltsfoot is a European import, but around here it is not invasive enough to be a pest.
For a fuller description, see the Tussilago farfara reference page.
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.
