Sand-verbena is a genus of about 35-40 species of annual or perennial herbaceous plants in the family Nyctaginaceae . They are native to western North America, from Yellowstone National Park, Wyoming south to west Texas, California and northern Mexico, growing on dry sandy soils.

They make very attractive garden plants for hot, dry sandy sites.

Despite the name, they are not related to the vervains (Verbena, family Verbenaceae).
