A species of petunia with a lax sprawing habit, spreading outward rather than upwards. flowers are only 2-inches wide, fragrant, violet-colored and cover the plants all summer long. it's an excellent choice for the front of the border or spilling over the edge of a container. p. violacea is a parent to many of the hybrids on the market today. it is a tough plant and has great heat tolerance for a petunia.
