Description

Petunia × hybrida plants were originally produced by hybridisation between P. axillaris (the large white or night-scented petunia) and P. integrifolia (the violet-flowered petunia) and other members of its complex, including Petunia inflata. P. axillaris bears night-fragrant, buff-white blossoms with long, thin tubes and somewhat flattened openings. The scent molecules emitted by the hybrids are generally similar to those from P. axillaris.
