Solanum — 43 species

Solanum is a vast, ecologically diverse genus in the nightshade family, encompassing food crops such as tomato, potato, and eggplant alongside ornamental and wild species. Light requirements span full sun for fruiting species to bright indirect light for ornamentals, while watering needs vary considerably by species but generally favour consistently moist, well-drained soil during active growth. All Solanum species are toxic to cats and dogs — foliage, unripe fruit, and stems contain solanine and related glycoalkaloids — so treat the entire genus as a pet hazard regardless of edible-crop status.
