Texas Poppy-Mallow
A vivid trailing perennial survives in a narrow stretch of west-central Texas where river terraces, open soil, and disturbance remain in balance.

Artwork inspired by Melissa Miller
Texas poppy-mallow produces sprawling rough-haired stems and large wine-red to magenta flowers with the mallow family’s central column. It occupies open sandy or gravelly soils on terraces and disturbed grasslands in a small area of the upper Colorado River basin, where competition and vegetation height matter.
Conversion, herbicide, road and utility work, altered disturbance, invasive plants, grazing pressure, and small separated populations threaten survival. Because some habitat occurs along rights-of-way and private land, a roadside bloom is not an invitation to stop unsafely or trespass. Photograph from legal access and never dig a plant.

Good to know
Several Callirhoe species are called winecups, and flower color alone is not enough. Exact range, leaf and stem characters, and expert verification matter; garden-center “winecups” may be another species or selection.
