Other names and notes
(Old Man's Beard, Devil's Darning Needles). A vine which you will usually spot via its' flowers which will be lying atop other vegetation. The flowers, occurring in stalked clusters from the leaf axils, have four white or cream color sepals and many stamens on the male flowers. Flowers can be male (staminate), female (pistillate) or perfect.; stems are square-like near branch junctions, leaves are 3 leaflets, coarsely toothed. Leaf stalks twist around other objects for support. In the fall the seed head is a set of beard-like tufts of plumed achenes, hence the other common name of "Old Man's Beard". The plant can be trained to grow on a trellis in the home garden. It does require full sun and it can become invasive. You will find it in many places in the Upland Garden. Certain species of Clematis, particularly C. flammula (Sweet-scented Virgins Bower) are poisonous as they contain an alkaloid, Clematine, which is a violent poison. C. virginiana is not known to be particularly hazardous but care should be taken in handling it. Clematis in the Greek refers to long supple branches and referred to an ancient plant. The common name, Virgin's Bower, is believed to come from the flowers which, when abundant, can form a cascade of white - white being a plant color referencing virginity.

Notes: Eloise Butler's records show that she collected plants of this species on Sept. 17, 1907 in Minneapolis on 4th Ave. between 24 the 25th Street. On July 11, 1911 she noted that it was also already growing in the Garden. It is listed on Martha Crone's 1951 census of Garden plants. It is found widely across Minnesota but not in all counties. It is one of three wild Clematis in the Eastern half of the United States, it's range extending as far west as the Dakotas, Nebraska and Kansas. Of these three, two are present in Minnesota, this one and "Purple Virgin's Bower", C. verticillaris.
