| Distribution | More-or-less throughout the Sandhills; also the southern outer Coastal Plain, northern Piedmont, and Alexander County (northwestern Piedmont).
Native of the central portion of the U.S. and southern Canada, but the natural boundaries are poorly known. Adventive on the Atlantic Seaboard, at least. | |
| Abundance | Uncommon to frequent in the Sandhills; apparently rare elsewhere but to be expected. In several places in the Sandhills, plants have numbered in the thousands. Plants may not re-appear in the same field in successive years. | |
| Habitat | Sandy fields, fallow cropfields, roadsides, railroads. It often co-occurs with the very common native Canada Toadflax (L. canadensis). | |
| Phenology | Flowering and fruiting March-May. | |
| Identification | This exotic species is very similar to Canada Toadflax, but the plants are taller, the leaves broader, and the flowers are much paler: pale lavender with a whitish palate (never medium to sky blue as in L. canadensis). When seen in the field the differences are obvious. No intermediates have been seen. | |
| Taxonomic Comments | Also known as Nuttallanthus texanus and L. canadensis var. texana.
