Spark Mix Shock Wave Petunia- These petite Baby Waves come in a mix that includes Coconut, Pink Shades, and Denim colors. Flowers are 1-1/2 to 2 inches across, about 1/2 to 3/4 the size of regular Waves. Fast-to-fill, mounding, 8 to 10 inch tall plants are less day-length sensitive than other Wave petunias so they-re earliest to bloom. They tirelessly produce incredible numbers of blossoms that recover quickly from rain and overhead watering.
