Little white stars that come out in the afternoon; they came over as a garden plant, but they found our climate hospitable and now can be found in lawns and at the edges of parking lots. These flowers were blooming in the Homewood Cemetery.

Great White Trillia blooming along the Trillium Trail in Fox Chapel.

Common Blue Violets normally bloom in a narrow range of shades from deep violet to deep purple. We do, however, sometimes find flowers in a range of shades from pale lavender to pure white, as well as flowers with white flecks. Most of these flowers were blooming in a lawn in Highland Park among a large population of the regulation violet-colored violets.
This one was blooming near Saw Mill Run in Seldom Seen.
It is possible that some of these plants are other closely related species, or even hybrids. Botanists themselves have trouble sorting violets: Viola papilionacea, for example, was commonly regarded as a separate species from V. sororia (though Gray said that V. sororia “passes into” V. papilionacea) but is now subsumed by its sister, which is called “sororia” (“sisterly”) precisely because it looks so much like some other species in the genus. In addition, Fernald’s revision of Gray’s Manual of Botany lists eleven other species with which Viola sororia hybridizes. At that point, Father Pitt gives up and simply says these are probably the same species, but corrections from botanists with better eyes are welcome.

Also known as Crinkleroot. A close relative of the Cutleaf Toothwort (Cardamine concatenata), but easily distinguished by its pair of broad leaves with three leaflets. These plants were blooming along the Trillium Trail in Fox Chapel.
For a description, see the Cardamine diphylla reference page.
Violets are difficult to sort out, and this species is similar to the Canada Violet (V. canadensis), also fairly common in our area. Note, however, the rounded leaves with rounded teeth, the long spur of the flower, and the almost complete lack of yellow at the bases of the petals; these things persuade us that this is V. striata. Corrections, however, are always received with gratitude. These plants were blooming abundantly along the Trillium Trail in Fox Chapel.
