Summary

Triodanis perfoliata, commonly known as Clasping Venus’ Looking-Glass, is an annual herb native to a variety of habitats including open woodlands, grasslands, and roadsides across North and South America. It typically grows to a height of 6–18 inches and produces distinctive wheel-shaped or bell-shaped violet-blue flowers. The flowering season extends from May to August, with the flowers being moderately showy. The leaves are 1/4–1 inch wide, scallop-edged, and shell-shaped, which clasp the stem, giving the plant its common name.

This plant is appreciated for its unique flowers and ability to grow in disturbed areas, making it a good choice for wildflower gardens and naturalized areas. It is also used in borders and as a filler in garden beds. Clasping Venus’ Looking-Glass thrives in full sun but can tolerate partial shade. It prefers well-drained soils and requires medium amounts of water, making it relatively easy to maintain. While it is not known for significant problems with diseases or pests, it can self-seed prolifically under ideal conditions, which may be considered undesirable in some garden settings.CC BY-SA 4.0
