Petunia (Solanaceae, Petunioideae)

What is the plant

As one of the most recognizable and beloved annual flowers, Petunias are a part of a gorgeous and versatile genus of plants that almost introduce themselves.

Petunia is a large genus of around twenty plants native to South America that has become a pretty popular addition to any garden or hanging basket. Petunias come in various sizes depending on the type and can range anywhere from 6in-18in (15cm-45cm) in height.

You can identify this popular annual flower mainly by the different groups of Petunia. Grandiflora are known for their large flowers and are excellent for hanging baskets. Milliflora are known for having much smaller flowers than other species of this genus. Floribundas have medium-sized flowers when blooming and are known as intermediate-sized flowers. Multiflora is the most common due to their durability and the rate at which they grow and reproduce.
