#straggler daisy

[stopandlook]

Scientific Name: Calyptocarpus vialis Common Name(s): Straggler daisy, horseherb Family: Asteraceae (aster) Life Cycle: Perennial Leaf Retention: Semi-evergreen Habit: Forb USDA L48 Native Status: Introduced (or not — see below the cut) Location: Richardson, Texas Season(s): Fall

Here in North Texas, this is an all-seasons, evergreen plant. Regarding its native distribution, the Lady Bird Johnson Wildflower Center notes the species is

Native to 5 southern coastal states, per ARS GRIN. USDA Plants does not consider it native anywhere in North America.

Both ARS GRIN (Agricultural Research Service Germplasm Resources Information Network) and USDA Plants are arms of the U.S. Department of Agriculture, so I have no idea who’s right. Native status aside, C. vialis is is the only species within its genus found in the United States, so at least it can’t be confused with other members of the same genus.
