Wild Flowers of Pittsburgh

Foamflower (Tiarella cordifolia)

Obviously this is one of our favorite flowers, since this is its third time being featured here. (More pictures are here and here.)

As we see here, some forms of this species grow leaves with deep red markings along the veins, and those forms have been developed into cultivated varieties with even more pronounced red markings. All the plants in this hollow in Schenley Park had the red markings on their leaves. They were blooming in early May, a little later than usual this year.

Gray describes the genus and the species:

TIARELLA L. FALSE MITERWORT. Calyx bell-shaped, 5-parted. Petals 5, with claws. Stamens long and slender. Styles 2. Capsule membranaceous, 2-valved; the valves unequal. Seeds few, at the base of each parietal placenta, globular, smooth. Perennials; flowers white. (Name a diminutive from tiara, a tiara, or turban, from the form of the pistil, which is like that of Mitella, to which the name of Miterwort properly belongs.)

T. cordifolia L. Leaves from the rootstock or summer runners, heart-shaped, sharply lobed and toothed, sparsely hairy above, downy beneath; stem (1-4 dm. high) leafless or rarely with 1 or 2 leaves; raceme simple; petals oblong, often subserrate. Rich rocky woods, N. S. and N. B. to Minn., Ind., and southw. in the mts. Apr.-June.
