is a trumpet shaped, widely-cultivated genus of flowering plants of South
American origin, in the family Solanaceae. Petunias are usually
diploid with 14 chromosomes and are infertile with other petunia species.
The popular flower got its name from French, which took the word petun
'tobacco' from a Tupi-Guarani language. Most of the varieties seen
in gardens are low-lying hybrids annuals that brag of their
diversity of brilliant color and attractive green foliage. They bloom all
summer with little maintenance and make perfect centerpieces to containers
and hanging baskets and serve as good low bordering color to gardens.
