Also called oyster-flower or goat’s-beard. There are three similar species, all naturalized from Europe; this one can be distinguished by the “peduncle upwardly enlarged below the head,” as Fernald’s revision of Gray explains. We can see what that means in the picture below: note how the flower stem—the “peduncle”—thickens as it goes up toward the base of the flower head.
These plants were growing in a gravely patch of ground beside Banksville Road in Banksville.
The common name “Cleavers” refers to the way these plants stick to clothing or animal hair. The stems are covered with downward-facing prickles that serve two purposes. First, they discourage hungry little critters from crawling upwards. Second, they stick to passing animals and people, so that, when the plant has gone to seed, it will break off, and the seeds will be distributed somewhere else after the broken stem has hitched a ride. These plants were blooming in Bird Park in Mount Lebanon.

Also known as Meadow Anemone, and by some botanists placed in the genus Anemonastrum (making it neuter, Anemonastrum canadense). This is a rare plant in the Pittsburgh area; here in the southern extremity of its range, the stations are sparse and widely separated. This plant was blooming in Bird Park, Mount Lebanon. There is a possibility that it was intentionally introduced, but the USDA PLANTS database does record Anemone canadensis as native to Allegheny County.
For a description of the species, see the Anemone canadensis reference page.
Also known as Myosoton aquaticum, depending on the mood of the botanist. This is a beautiful large-flowered Chickweed that would make a good shade-garden planting. When we say “large-flowered” or “giant,” of course, we mean in relation to most other chickweeds. By other standards this is a smallish flower. These plants were blooming in open woods in Bird Park, Mount Lebanon.
For a description of the species, see the Stellaria aquatica reference page.
A water-loving native Iris with spectacular blue to violet or purple flowers marked with white and yellow. These plants were growing by a stream in Bird Park, Mount Lebanon.
