Black nightshade

Black Nightshade

Black nightshade is a common herb or short-lived perennial shrub, found in many wooded areas, as well as disturbed habitats.

Black nightshade grows in soils with low Calcium and Phosphorus but with high Potassium and Magnesium. It may indicate that the soil has low organic matter and is compacted.

The plant often indicates that the soil has the anaerobic types of bacteria meaning they operate in an environment lacking adequate oxygen. Beneficial microbes have difficulty functioning in this soil.
