"The supertunia mini vista violet star petunia is a standout member of the Petunia x hybrida family. Unlike older varieties that become “leggy” by mid-summer, this specific selection is bred for a compact, mounded, and trailing habit that maintains its shape beautifully. Gardeners love this plant because it offers a dense, continuous carpet of violet-purple blooms with a striking white star pattern. Because it is part of the Supertunia Mini Vista series, it is specifically engineered to be more heat-tolerant and vigorous than traditional petunia types."
