The Fascinating History Of The Petunia Name
The name “Petunia” comes from the French word “pétun,” which means “tobacco.” This name was given to the plant because of its resemblance to the tobacco plant, both in terms of appearance and fragrance. Ancient civilizations, such as the Maya and Inca, believed that the scent of petunias had the power to ward off underworld monsters and spirits.

These annual plants bloom profusely from early summer until frost, adding a burst of color to any garden.
The Hybridization Of Petunias: Introducing Petunia × Atkinsiana
Most petunias seen in gardens today are hybrids, specifically a variety called Petunia ×atkinsiana. These hybrids are created through the process of crossbreeding different petunia species, resulting in unique characteristics and color variations. The hybridization of petunias has allowed for the development of countless cultivars, each with its own distinct traits.
The introduction of Petunia ×atkinsiana marked a significant milestone in the world of petunias. These hybrids exhibit traits that make them ideal for cultivation in home gardens. They are known for their compact size, reaching heights of 15-25 cm, and are often found in summer garden beds. Additionally, there are sprawling, long-stemmed balcony petunias that grow up to 46 cm and are commonly potted in hanging baskets and window boxes.

It is worth mentioning that Calibrachoa, another genus, is often debated as part of the Petunia genus. Some botanists consider Calibrachoa plants to be a part of the Petunia genus, although this classification is not universally accepted. The debate around the relationship between these genera adds to the complexity and intrigue of the petunia family tree.
