Black nightshade is a low-growing annual herb with small white flowers followed by dark berries. This weedy plant often appears in disturbed soils and garden beds without invitation. All parts of the plant are potentially toxic, making it unsuitable for most residential landscapes.

In an HOA neighborhood

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

  • Considered a weedy species
  • Toxic berries pose safety concerns
