We suggest Red or Rose Pirouette Petunia as replacements
Purple and white double petunias, an All America Selection. These distinctive bi-colors really struck our fancy. They perform well in a hanging basket although they are quite tall, 15 inches, and erect so may do even better in other containers. The blend of the dark color with the white is just perfect, about 25% white so it is more than fringed.

Care: When grown in containers petunias need to be fertilized and watered regularly. This will keep the plants blooming all season long. During the heat of summer, they will need to be watered a few times a week. When growing petunias in the ground amend the soil with compost before planting. Apply a liquid fertilizer every 1-2 weeks or use a time-release fertilizer at planting time.
