Triodanis perfoliata, the clasping Venus' looking-glass or clasping bellflower, is an annual flowering plant belonging to the family Campanulaceae (bellflower family). It is an annual herb native to North and South America, the natural range extending from Canada to Argentina. It is also naturalized in China, Korea and Australia.

Description

T. perfoliata is an annual plant that grows to a height of 10–46 centimetres (4–18 in), occasionally taller, with a central, unbranched, lightly hairy stem featuring alternate leaves that clasp the stem. The leaves are light green, rounded, up to 2.5 centimetres (1 in) long, and are scallop-edged and shell-shaped. Both the stem and the leaves contain a milky sap.

On the upper part of the stem, 1-3 flowers emerge from the leaf axils, although only 1 of these flowers will be blooming at any one time. These flowers are wheel-shaped or bell-shaped, violet blue (rarely white), and approximately 1.3 centimetres (.5 in) across. They have 5-lobed corollas and are radially symmetrical. There are flowers on the lower part of the stem but they do not open, although they do produce seed. The plant produces a small, many seeded capsule with 2 or 3 sections for fruit.
