Petunia integrifolia Hooker-Schinz-Thellung
Solanaceae (Nightshade) Family
Old Fashioned Petunia is a semi-prostrate or upright, hairy perennial. Its preferred habitat is open meadows, roadsides and gardens. Distribution is throughout the Escambia region.
The leaves are clammy, elliptic (widest at the middle) to ovate. Most leaves have no teeth and no lobes. The upper leaves tend to be opposite on the stem while the lower leaves are placed alternate. The leaves may be sessile or occasionally on short leaf stalks. The color is muted green above and paler below.
The flowers are about 2 inches across; pink, purple or white. Flower arrangement may be solitary or as many as 3 arising from the leaf axil. The calyx is 5-lobed; the corolla is funnel shaped or salverform, nearly symmetrical in shape. The corolla lobes are plicate in bud, the stamens are bisexual in nature. The hypogynous (a structure formed by the fusion of sepals, petals and stamens) is fleshy. The stigma is dilated and capitate (compact and head-like).
Fruit is a capsule.
The Old Fashioned Petunia escaped from cultivation and has become naturalized in most parts of the southeast. This prized garden flower is the standard for today's hybrid petunias, thus the Latin species name.
