Hairy nightshade is an annual with plant growth beginning in early summer.  It is found in waste areas and in cultivated fields. This species contains toxic alkaloids, especially in the berries.   The mature plants are 12 to 24 inches tall.  The foliage is spreading, hairy, and may feel sticky when handled. Flowers have 5 white petals with yellow centers that develop into green fruit containing very small seeds. Each berry is enclcosed by an enlarging green calyx. As the fruit matures, the calyx cups the lower half of the greenish or yellowish fruit.
