Solanum elaeagnifolium, commonly known as silverleaf nightshade or white horsenettle, is a flowering plant native to the Americas and considered an invasive weed in many parts of the world. It belongs to the Solanaceae family, which includes tomatoes, peppers, and potatoes. Some synonyms for Solanum elaeagnifolium include sticky nightshade, silverleaf, silverleaf nettle, and buffalo-bur nightshade. This plant can grow up to 4 feet tall and has beautiful purple flowers that bloom in the summer. However, it is considered a nuisance due to its tough, spiny leaves and ability to rapidly spread and dominate areas.
