Surfinia petunias bloom continuously all season long, and they hold up well even in wind, rain and summer heat. The first cross of a wild petunia and a propagated seed hybrid, Surfinia petunias are number one in Europe, where brilliant cascades fall from window boxes everywhere. Not only attractive to the human eye, but to birds, butterflies, and hummingbirds as well. Height 6-10″, full sun. Heat tolerant. Photo courtesy of Ball Seed.
