Silverleaf nightshade (Solanum elaeagnifolium)
Silverleaf nightshade (Solanum elaeagnifolium) is a perennial plant species that is native to North and South America. Controlling Silverleaf nightshade in your pastures is key to producing healthy forage and livestock. The plant can grow in a wide range of soil types and climatic conditions, and its hardiness allows it to outcompete native plants for resources such as water, nutrients, and sunlight.
The plant gets its name from the silver-colored leaves that cover the stems and branches. These leaves are thick and waxy, which helps the plant to conserve water and resist drought. The plant also produces small violet, light blue or white flowers and is one to three feet tall. Stems are sparsely covered with short yellow thorns. The leaves have wavy margins and are lance shaped to narrowly oblong. Leaves and stems have a dense silvery covering of hair.
Silverleaf nightshade prefers warm- temperate regions and often grows in disturbed soils in the Southwestern United States and Mexico. It is an invasive species that has successfully spread outside of its native range to become a noxious weed in twenty-one states in the US. It can occasionally be found even farther north than Kansas.
