Petunia integrifolia

I love the more wildling look of the older petunias and this one is hands-down the easiest of them to grow. It rapidly forms a large mound that trails over the edges of window boxes/hanging baskets or winds around other plants in the garden, covered in non-stop blooms. It is also the only taller/bushier petunia I've grown that the squirrels here usually leave alone and whose leaves the slugs here rarely eat.

This is a hot perennial in south Alabama! It is an excellent ground cover and tolerates humid heat of the southern Alabama climate without fail. I grows in the sand on the beach. It is somewhat aggressive, evergreen and blooms all year. Absolutely a fabulous petunia!

Grows very easily from seed and flowered all summer long. I already have seedlings where it has reseeded in one of the containers that I had it growing in this summer.

I also want to add that here in my zone 5-6 garden in western NY, this petunia does reliably reseed the next year. From one basket that I planted last spring I made up 3 large baskets from reseeders this spring after the old basket sat out in the garden all winter long and the new seedlings started to bloom when they were only about 2 inches tall.

Addition to my original description: I have had reseeders since the first year growing this plant. This year I filled two hanging baskets and bordered one new flower bed. I also have several growing in various locations around the garden. It just keeps on giving. By the way it is stunning with Salvia guaranitica 'Black & Blue'

Grows easily from seed (available from JL Hudson's). Beautiful small pink/magenta flowers; no dead-heading; spreads and weaves easily among the perennials.

This plant grows wild all over Brooklyn, New york coming up in every crack and crevice,blooming all summer long. They are not perennial here,at least I don't think so. But I've been seeing them in every dooryard garden for as long as I can remember. A very beautiful and loyal plant.

A species petunia with a lax sprawing habit, spreading outward rather than upward. Flowers are only 2-inches wide 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.
