Petunia is a genus of flowering plants in the nightshade family (Solanaceae) native to South America. The best-known form is the common garden petunia, a widely grown ornamental hybrid valued for its colorful trumpet-shaped flowers.
What it is
Petunias are mostly annual herbs with sessile, usually oval leaves and showy, funnel-shaped or trumpet-shaped flowers. The genus belongs to the nightshade family Solanaceae and is native to South America. The name is linked to the Brazilian indigenous word for tobacco, reflecting the plants’ relationship to other nightshade-family species.
Cultivation and uses
The common garden petunia (Petunia × atkinsiana) is a popular ornamental hybrid grown for colorful blooms. It is often treated as an annual in temperate regions, though it can be perennial in warmer climates. In Canadian gardens, petunias are widely used as bedding plants, in window boxes, and in containers during the frost-free growing season.
Pollination and reproduction
Most petunia species are insect-pollinated, but at least one species, P. exserta, is pollinated by hummingbirds. After flowering, seeds are produced in small dry capsules.
