This is the wild species from which the modern petunias have descended. The trailing plants have 2" wide, rosy-purple, trumpet-shaped flowers. They are wonderful at the edge of a garden path, tumbling over rocks, or growing in containers. The plants grow to about 10" tall and 18" wide.
Petunia integrifolia is a tender perennial, hardy in zones 9-11. But it is usually grown as an annual. It blooms quickly from seed, and it may self sow in warm spots where it's happy. Also called Violet-Flowered Petunia and Petunia violacea.
Sowing Petunia Seeds:
Sow indoors 6-8 weeks before the last frost date. Sow on the surface. Full sun.
