Silverleaf Nightshade

Silverleaf nightshade, Solanum elaeagnifolium

Silverleaf nightshade is an upright perennial that reaches heights up to 1 m (3 ft) with tiny, silvery matted hairs covering the plant. The hairs also give it the name of whiteweed and white horsenettle. It can be found throughout most of the United States as well as Mexico and can become a serious weed of prairies, open woods, and disturbed soils. Silverleaf nightshade blooms from April until October with the flowers giving way to round, yellow fruits. As with other wild members of the nightshade family, all parts of silverleaf nightshade are poisonous. While many native birds species and mammals consume the berries, the glycoalkaloid compounds within the leaves and fruit are toxic to human and livestock.
