The scientific name for petunia is Petunia x hybrida. This plant is mostly used for ornamental purposes, given that it is found in a wide variety of colors, sizes and shapes.
The petunia is an annual plant, meaning that the plant completes its entire life cycle in one growing season. The life cycle includes seed germination, vegetative growth, flower growth and the production of seeds.
Completing its life cycle in one growing season requires replacing annual plants every year. Petunias can be planted in flower beds, window boxes, plant containers and hanging baskets.
Problems that can occur with petunias include aphid infestation and root rot.
