    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.

  • Common Vetch (Vicia sativa)

    Photographed May 29.

    An adaptable weed also extensively planted as forage. The tiny flowers are easily missed in a weed patch, but a close look reveals that they are perfect miniature sweet peas. Ants seem to love it, and we have several pictures here of ant guests enjoying the plant and probably pollinating the flowers. These vines were all blooming on the grounds of Fallingwater in Mill Run.

    Hog Peanut
    Photographed August 22 with a Konica Minolta DiMAGE Z6.

    A vine that twines its way through the underbrush along creeks and streams, dangling clusters of flowers in white, pink, or purple. These flowers produce seeds, but the vine also grows less showy flowers near the ground that turn into a single underground seed, like a peanut. These vines were found in Bird Park in Mount Lebanon.
