A petunia is a type of flowering plant popular in gardens and flowerpots. Petunias bloom in bright colors like purple, pink, red, white, and yellow, with trumpet-shaped flowers that open wide in the sunshine. They're favorites for window boxes and hanging baskets because they grow quickly, bloom all summer long, and cascade beautifully over the edges of containers.

Petunias are native to South America but now grow in gardens worldwide. They're relatively easy to care for, which makes them perfect for beginning gardeners. Many people choose petunias when they want to add cheerful color to a porch, deck, or garden bed without too much fuss.

The flowers can have a light, pleasant scent that attracts butterflies and hummingbirds. Some varieties are small and compact, while others spread out and cover large areas. Gardeners often plant petunias in spring after the last frost, and the plants keep producing new flowers until fall arrives and the weather turns cold.
