What's the best Wave petunia for covering a sunny hillside?
I have a sunny (South facing) grass covered hillside that I want to cover with Wave petunias. The total area is approx. 15'x15'. Which type of Wave is best for covering large areas? Will the Wave petunias grow over grass? I plan on growing from seed and digging holes in the grass about 2 feet apart and letting them spread over the grass. Will this work?
