Three-flowered clematis (lat. Clematis terniflora).
A perennial plant, a species of the genus Clematis of the Buttercup family (Ranunculaceae). A semi-evergreen climbing plant with woody stems, leaf petioles and leaf axes can cling and twine around plant branches and other supports, acting as tendrils.
The leaves are opposite, shiny, consist of 3-5 leaflets, on petioles 2.5-4.5 cm long. The leaves are ovate or narrowly ovate, 2.5-8 cm long and 1-4 cm wide, rounded at the base, heart-shaped or broadly wedge-shaped, acute or obtuse, entire, papery to thin-skinned, sparsely hairy on both sides, soon becoming bare.
The flowers are collected in multi-flowered axillary and terminal corymbs, 1.4-3 cm in diameter, on pedicels 0.5-3 cm long, the general peduncle 1-7 cm long. Bracts linear to oblong, 1-5 cm long. Often, in addition to bisexual flowers, the inflorescence contains staminate flowers.
An ornamental plant with fragrant white flowers, but is an invasive species in some regions. Good pollen plant and minor honey plant. It is well visited by bees to collect pollen and nectar.
