Petunia — 14 species
Part of the Nightshade family family (Solanaceae)
Petunia is a genus of flowering annuals and tender perennials from South America, celebrated for their prolific, trumpet-shaped blooms in nearly every colour. Popular series include Wave, Supertunia, and single-colour violets. They grow best in full sun with at least five to six hours of direct light daily and prefer moderately moist, well-drained soil; water when the top inch feels dry and avoid prolonged soggy conditions. Petunias are non-toxic to cats and dogs according to the ASPCA, making them one of the safer choices for pet-friendly gardens and hanging baskets.
