Fringed Polygala – An Instant Favorite

It’s love at first sight when a hiker catches his first view of the shocking pink flowers of fringed polygala (Polygala paucifolia). Its strangely shaped flowers might fool someone into thinking that this is a member of the orchid family, or perhaps the pea family. No other flower in the Northeast looks quite like it—that is no other flower of its size (ca. 1.5 inches long). The other members of the same genus are so tiny that they require examination with a hand lens to see the detail.

The flaring wings and propeller-like fringe on the flower’s tip give it the appearance of a small magenta airplane. Only by pressing down on the “fuselage” of the flower can you find its reproductive structures. The two sides of the flower that form the forward-pointing portion open up and the stamens and pistil are exposed—just as they would be if a bumblebee were to land on the flower. And, indeed, like many of our spring wildflowers, bumblebees are the principal pollinators of fringed polygala.

Fringed polygala often grows in large colonies and particularly favors mossy sites. A small plant, the contrasting glossy green leaves and pink flowers make a striking ground cover.

Wildflower Wednesday — Early Saxifrage

Micranthes_virginiensis

A mature plant of early saxifrage growing
on a moss-covered rock cliff. Some of the
basal leaves are still red.

Early Saxifrage – The name “saxifrage,” from the Latin saxum meaning “rock” and frangere, “to break,” was given to members of the genus Saxifraga because many saxifrage species grow in crevices of rock cliffs where they appear to have caused the cracks in the rock. Our own early saxifrage often grows in just such places.

The plant maintains a basal rosette of leaves throughout the winter, the toothed leaves sometimes becoming bright red during that season. In spring the leaves turn green, and the flower buds at the center of the rosette open, first at ground level, and then on ever elongating and branching stems until the plant reaches 15” in height.

Saxifrages, in general, are known for their hardiness, growing in high mountains from the Alps, to the Andes, to the Himalayas. In fact, one saxifrage, Saxifraga oppositifolia, is one of only four plant species to grow in the northernmost place on earth where plants are able to grow, at 83°24’ N on Lockwood Island, off the north coast of Greenland. Recent molecular studies have resulted in almost all species of our eastern North American saxifrages being transferred to the closely related genus Micranthus; thus this species, formerly Saxifraga virginiensis, is now known as Micranthus virginiensis.
