  • Yarrow (Achillea millefolium)

    Yarrow (Achillea millefolium) blooming in Schenley Park, Pittsburgh
    Photographed June 12.

    Sometimes mistaken for Queen Anne’s Lace, to which it is not related; Yarrow is a composite, meaning that each of those little flowers in the bunch is itself a head of multiple flowers. This plant was blooming in an open field in Schenley Park.

    For a description of the species, see the Achillea millefolium reference page.

  • Alfalfa (Medicago sativa)

    A common forage crop that often plants itself. The deep violet flowers in a loose clover-like head are distinctive. These plants were blooming on a bank by the street in Beechview.

  • Yellow Hawkweed (Hieracium caespitosum)

    Yellow Hawkweed (Hieracium caespitosum)
    Photographed May 29.

    A common weed of lawns; it closely resembles the more spectacular Orange Hawkweed (H. aurantiacum) in everything but color. This one has many common names, some of which it shares with the orange species, including King Devil, Devil’s Paintbrush, Yellow Paintbrush, and Fox-and-Cubs. Many current botanists place both in the genus Pilosella, so that (making the adjective agree in gender) it becomes Pilosella caespitosa; but there are still arguments about that, and old Pa Pitt will stand back and let the professionals sort it out. These plants were blooming in a field near Farmington.

  • Blue-Eyed Grass (Sysirinchium angustifolium)

    Photographed May 29.

    The plants are invisible in the grass until they bloom, and even then it is easy to miss the little flowers. Once you see them, though, you will probably spend a while admiring them. These plants were blooming in a field near Farmington.
