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.

Wildlife value
The small white flowers attract bees, flies, and beetles during the summer months. Birds may eat the berries, though the plant's toxic properties limit its overall wildlife value.
