Small Venus’ Looking-Glass: A Charming Native Annual for Wildflower Gardens

This petite annual brings a touch of whimsy to naturalized landscapes with its tiny, mirror-like flowers that seem to wink at you from the garden bed.

As a member of the bellflower family, this charming little wildflower produces small blue to purple flowers with distinctive white centers that give it its looking-glass moniker.
You might also see this plant listed under its botanical name Triodanis biflora, or encounter it in older references as Specularia biflora. Whatever you call it, this native beauty has been quietly decorating American landscapes for centuries.
Where Does It Grow Naturally?
Small Venus’ looking-glass is native to much of the lower 48 United States, calling home to an impressive 24 states from coast to coast. You’ll find it naturally occurring in Alabama, Arizona, Arkansas, California, Florida, Georgia, Illinois, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nebraska, New Mexico, New York, North Carolina, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, and Virginia. It has also been introduced to Hawaii, where it grows as a non-native but naturalized species.
Should You Plant It in Your Garden?
For most gardeners in the continental United States, small Venus’ looking-glass makes an excellent addition to native plant gardens and wildflower meadows. Here’s why you might want to consider it:
