One of my favorite native vines, the Purple Leatherflower (Clematis pitcheri), typically climbs over and around woodland margins, road cuts, fence rows, and disturbed ground such as construction sites. While its stems can grow to a length of ten feet or more, its flowers usually are less than an inch long. Solitary and simply shaped, the sepals of the blue-to-purple flowers have recurved, slightly ruffled margins; the plant blooms from late spring through summer.
The genus name is derived from the Greek klematis: a word which designates climbing plants. The specific epithet pitcheri honors Dr. Zina Pitcher (1797-1872), a surgeon with the United States Army, Regent of the University of Michigan, and botanist in the Great Lakes region.
Seeds begin to form even while the plant still is blooming. Held in clusters, they mature from light green to dark red or brown, with slightly hairy tails that some describe as spider-like.
The flowers are pollinated primarily by bumblebees, although other insects such as flower-feeding thrips and caterpillars of various Thyris moth species feed on the foliage. The vine is used as cover and nesting habitat by songbirds, and although no specific butterflies are associated with the plant, this Painted Lady (Vanessa cardui) seems to have found it a congenial resting place. Whether it was sipping a bit of leftover nectar or pondering its next stop on the vine, I can’t say.
