Petunia is a type of flowering plant that belongs to the family of nightshades.There are 35 species of petunia that originate from South America. Petunias are low-growing, bushy to spreading tender perennials usually grown as annuals. Their soft, thick leaves are slightly sticky to the touch. Trumpet-shaped flowers have a single set of plain-edged petals, or can be doubled, ruffled, or fringed and come in colors from light pink through dark red, and pale blue through deep purple. Petunia cultivates in areas that provide at least 5 to 6 hours of sun per day, on a well-drained, fertile soil. It doesn’t tolerate frost. Petunias are cultivated because of their ornamental flowers that are available in variety of colors and shapes. Whether in hanging baskets or containers on tables or a front porch, growing petunias in pots brings out vibrant color throughout the summer to whatever area you choose
