Supertunia Flower Seeds – Premium Hybrid Trailing Garden Variety

Overview

Supertunia Seeds grow into vigorous, hybrid petunia plants that deliver season-long color and abundant blooms. Known for their mounding and trailing growth habit, Supertunias are ideal for hanging baskets, garden beds, containers, and landscape borders.
