Solanum elaeagnifolium

Other common names include prairie berry, silverleaf nettle, white horsenettle or silver nightshade.

Leaves and stems are covered with downy hairs (trichomes) that lie against and hide the surface, giving a silvery or grayish appearance.

The plant produces glossy yellow, orange, or red berries that last all winter and may turn brown as they dry.

[8] It is considered a noxious weed in 21 U.S. states and in countries such as Australia, Egypt, Greece, India, Israel, Italy, South Africa, and Zimbabwe.

A five-year study found that frequent mowing of silverleaf nightshade contributes toward making it a 'superweed', with a deeper taproot, a spikier stem, and greater toxicity to grazing caterpillars.

[14] Ingestion of silverleaf nightshade has been implicated as a cause of ivermectin toxicosis in horses given the recommended dosage of the drug.

[16] The Pima Native Americans used the berries as a vegetable rennet, and the Kiowa used the seeds together with brain tissue to tan leather.
