About Silverleaf nightshade
Solanum elaeagnifolium, also known as Silverleaf Nightshade, is a perennial herbaceous plant or subshrub native to North America, characterized by its stems and leaves covered with silvery or stellate hairs that give it a distinctive appearance. It produces purple or lavender flowers with prominent yellow stamens, followed by bright yellow to orange spherical berries that persist on the plant. Although attractive for its foliage and fruits, it should be handled with caution as all its parts are toxic if ingested.
Native range
Southwestern United States and northern Mexico
Care tips
This plant thrives in full sun and tolerates a wide range of soils, though it prefers well-drained, not overly rich ones. It is very drought-tolerant once established, so watering should be sporadic, allowing the soil to dry out completely between waterings. A common mistake is overwatering, which can lead to root rot. Due to its invasive nature in some regions, it is recommended to control its spread and prevent seed dispersal.
