Description
 
 

Sweet autumn virgin’s bower is a climbing and scrambling, perennial, semi-woody vine that rises from an elongated rhizome.

The stems are green and hairless when young, becoming brownish-green to brown with age. They are keeled with one or more longitudinal ridges. They extend from 10 to 20 and can climb 6 to 9.

The leaves are opposite, compound, on leaf stalks up to 1½ long, and divided into usually 5 but sometimes 3 leaflets. The leaflets are attached to a central axis by a leaflet stalk up to 1 long. The central stalk of the leaflet and the leaflet stalks are adapted for coiling by spiraling around objects (twining). It is by this means that the vine is able to climb.

The leaflets are egg-shaped to lance-shaped, nearly circular, or narrowly triangular, up to 2½ long and 1 wide. They taper to a blunt, rounded tip. The margins are untoothed but can be untoothed. The upper surface is green and hairless. The lower surface is dull light green and hairless or may have short, appressed hairs along the main veins.

The inflorescence is dense, branched, stalked clusters, with 3 to 12 large flowers, rising from the leaf axils on hairless or sparsely hairy stalks.

Male and female flowers may be borne on separate plants, though most plants have flowers with both male and female parts (perfect). The flowers are 1½ to 2 wide. There are 4 white, widely-spreading, petal-like sepals. There are no petals. The sepals are hairy along the margins on the lower surface. There are about 50 stamens with white filaments and 5 to 10 pistils.

The fruit is an egg-shaped, flattened achene containing a single seed. The styles remain attached, becoming ¾ to 2 long, green, silky, and curled. The are covered with long white hairs, giving them a feathery appearance. They eventually turn brown.

Virgin’s bower (Clematis virginiana) leaves are divided into 3 leaflets. The leaflets are on short leaf stalks long or less, shallowly lobed, coarsely toothed, and taper to a sharp point. The flowers are much smaller, only about wide. The elongated styles attached to the achenes are hairless.

Western blue virgin’s bower (Clematis occidentalis var. occidentalis) leaves are occasionally 1 to 3 lobed and taper to a sharp point. The inflorescence is a single, sometimes 2, flowers rising mostly from the leaf axils. The flowers are bell-shaped and reddish violet.

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.
