Reply:The garden plants are hybrids between species so they are Petunia x hybrida.

The parent species of our hybrids include;


Petunia axillaris ( night fragrant for moth pollination)

Petunia integrifolia

P. violacea


Petunia ascillaris hybrids include the Supertunia and Surfinia Series plants


"In the genus Petunia, pollination partnerships vary. P. axillaris attracts hawkmoths but P. integrifolia attracts bees as pollinators. The species specialize with profound differences in floral morphology, fragrance, petal color, and nectar. Morphology changes include nectary volume,


concentration and composition of the secreted nectar. Fragrance differences are in both timing and


emission levels of volatile phenylpropanoids.

The basic form of a petunia is 5 fused petals that make up the tubular corolla with 1 pistil and 5 stamens inside making it a bisexual flower. The leaves are simple and entire. Dicot flowers like this show petals in groups of 5 or 4 or multiple of these. (Monocots show 3 or multiples of three.)
