Discussion | Naturalized populations of Petunia integrifolia appear to have been more common prior to the 1960s, based on herbarium specimens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Petunia × atkinsiana is the most commonly naturalized of the three species and is often robust. When fertile, it can spread by seed from cultivation and become established in disturbed areas. Some herbarium specimens probably represent waifs; it is often difficult to determine from label data. Cultivated plants are available in a wide range of colors and color patterns. Only white to pale pink morphs were seen in specimens representing naturalized populations; other color forms may be fertile and may occur outside of cultivation.
