The seven Supertunia Raspberry Blast I purchased this spring have performed wonderfully. Unlike other petunias I have used (including Wave), these are full and loaded with blooms, not leggy. They attract both hummingbirds and butterflies, and those on the E/SE side of the house receiving more than eight hours of sun daily have done as well as those on the westerly side which receives partial tree shade.
