Bugleweed is common at the edges of ponds, often dangling over the water. Here we see it framed by the clouds reflected in a pond in the Allegheny Cemetery in Lawrenceville.

Spearmint (Mentha spicata)
Spearmint is especially common in urban yards and vacant lots, where it often escapes from cultivation. The prison isn’t built that can hold spearmint, which can be very invasive once you have it. But it’s such a useful herb that its sloppy manners are easy to forgive.

White Clover (Trifolium repens)
You see it everywhere, but do you ever stop to look at it close up? This is your chance. Take a moment to contemplate the beauty of white clover in an ordinary lawn.

Northern White Violet (Viola pallens)
Our most common violets are the violet-colored ones, but these white ones are often found in open woodlands. These grew in a woodland that was also liberally dotted with common blue violets and a scattering of yellow violets.

Great White Trillium (Trillium grandiflorum)
By Mayday woodland hillsides are covered with enormous colonies of this beautiful flower, especially in stream valleys. This one grew along the aptly named Trillium Trail in Fox Chapel; another large colony grows on a hillside in the Allegheny Cemetery in Lawrenceville. The genus Trillum has been variously placed in the families Liliaceae and Trilliaceae, but botanists finally seem to have settled on placing it in the family Melanthiaceae, where doubtless it will find a good home.
From Gray’s Manual of Botany: Trillium grandiflorum (Michx.) Salisb. Leaves less broadly rhombic-ovate; pedicel erect or ascending ; petals oblanceolate, often broadly so (4-6 cm. long), white turning rose-color or marked with green ; stamens with stout filaments (persistently green about the fruit) and anthers, exceeding the very slender erect or suberect and somewhat coherent stigmas; fruit subglobose. Rich woods, w. Que. and w. Vt. to Minn., Mo., and N. C.
