About Sticky nightshade
Solanum sisymbriifolium, commonly known as sticky nightshade or fire-and-ice plant, is a perennial herbaceous plant from the Solanaceae family, characterized by its stems and leaves covered in sharp spines. It produces white to violet-blue flowers followed by spherical red fruits resembling small tomatoes, and can be used in edible plant gardens or to add an exotic and defensive touch to the landscape.

Care tips
This plant thrives in full sun to partial shade and well-drained soil, preferably rich in organic matter. Watering should be regular, keeping the substrate moist but not waterlogged, especially during flowering and fruiting periods. Caution is advised when handling due to its spines, and consumption should be avoided as some parts of the plant can be toxic. A common mistake is underestimating its spreading capacity and allowing it to propagate unchecked in warm climates.
