What Is Holzinger’s Venus’ Looking-Glass?
Holzinger’s Venus’ looking-glass is an annual forb native to the lower 48 states. As a forb, it’s a non-woody herbaceous plant that completes its entire life cycle in a single growing season.

This native wildflower naturally grows across a broad swath of the south-central United States, including Arizona, Arkansas, Colorado, Kansas, Missouri, Nebraska, Oklahoma, Tennessee, Texas, and Wyoming. Its wide distribution speaks to its adaptability and resilience.
Why Grow This Native Wildflower?
