Indian-tobacco is a slender annual wildflower that produces spikes of small blue flowers from summer into fall. This native plant grows 6-30 inches tall with a narrow, upright habit that fits well in mixed plantings. Despite its common name, it is not related to commercial tobacco but gets its name from historical indigenous uses.

In an HOA neighborhood

Indian-tobacco takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Contains toxic alkaloids that may concern neighbors
  • Annual nature means gaps appear when plants die
  • Can self-seed unpredictably creating weedy appearance

Wildlife value

The tubular blue flowers attract bees, butterflies, and moths throughout the late summer blooming period. As a native annual, it provides nectar during a time when many other flowers are fading.
