The Wild Petunia grows to be about a foot in height. It is a hardy plant, blooming through June, July and August. It grows best in medium or medium-dry soils and full sun. Because it is somewhat aggressive, it does well as a ground cover, with a sidewalk or something to contain it. When mature, the seeds literally explode from the plant, traveling upwards of 10 feet! When in flower, Wild Petunia attracts a wide variety of insect pollinators, but the lavender blooms are especially attractive to long-tongued bees and butterflies.
