Description
 
 

Virgin’s bower is a climbing and scrambling, perennial, woody vine that rises from an elongated rhizome.

The stems are purplish and sparsely to moderately hairy, the lower part becoming brown and woody with age. They are keeled with one or more longitudinal ridges. They extend from 6½ to 23 and can climb 6 to 9.

The leaves are opposite, compound, on stalks up to 2 long, and mostly divided into 3 leaflets. The leaflets are attached to a central axis by a stalk up to long. The terminal leaflet is on a longer stalk than the two lateral leaflets. The central stalk of the leaflet is adapted for grasping by wrapping around objects. It is by this means that the vine is able to climb.

The leaflets are egg-shaped to lance-shaped, shalowly lobed, 1 to 3½ long, and to 3 wide. They taper to a sharp point at the tip with concave sides along the tip. The margins are usually coarsely toothed but can be untoothed. The upper surface is hairless. The under side is sparsely or densely covered with long, soft, straight hairs.

The inflorescence is dense, branched, stalked clusters, up to a few inches across, rising from the leaf axils on hairy stalks.

Male and female flowers are borne on separate plants, though some plants have flowers with both male and female parts (perfect). The flowers are about wide, with 4 white to greenish, widely-spreading, petal-like sepals. There are no petals.

The fruit is an egg-shaped achene containing a single seed. The styles remain attached, becoming up to 2 long, green, silky, hairless, and curled, eventually turning brown.

Similar Species

 
 

Sweet autumn virgin’s bower (Clematis terniflora) leaves are divided into usually 5 leaflets. The leaf stalk is twining. The leaflets are on a twining leaflet stalk up to 1 long, unlobed, untoothed, and taper to a blunt, rounded tip. The flowers are much larger, 1½ to 2 wide. The elongated styles attached to the achenes are covered with long white hairs, giving them a feathery appearance.

Western blue virgin’s bower (Clematis occidentalis var. occidentalis) leaflets are unlobed or occasionally 1 to 3 lobed. The inflorescence is usually one, sometimes two flowers rising mostly from the leaf axils. The flowers are bell-shaped and reddish violet. The elongated styles attached to the achenes are hairless.

Glossary

Achene

A dry, one-chambered, single-seeded fruit, formed from a single carpel, with the seed attached to the membranous outer layer (wall) only by the seed stalk; the wall, formed entirely from the wall of the superior ovary, does not split open at maturity, but relies on decay or predation to release the contents.

 

Axil

The upper angle where the leaf stalk meets the stem.

 

Compound leaf

A leaf that is divided into leaflets, each leaflet having the general appearance of a leaf, with all leaflets attached to a single leaf stem.

 

Twining

Growing in a spiral usually around a stem of another plant that serves as support.
