Supertunia Vista® Silverberry Petunia

Supertunia Vista Silverberry is a vigorous annual petunia with white flowers and a rounded, mounding form that trails over bed edges and container rims. Its broad growth makes it useful where a sunny planting can accommodate a spreading seasonal display. ## Placement and display The Proven Winners profile lists a mature garden height of 12–24 inches and a spread of 24–36 inches, with longer trailing growth possible in baskets. Use it in a large container, mixed planter, border, or mass planting, allowing room around neighboring plants. The flowers are white, and the display continues through spring, summer, and fall in a growing season. ## Growing conditions Place Silverberry in full sun or part sun. The grower rates its water need as average and its soil fertility need as average; keep container soil evenly moist and check hanging baskets more often during hot or windy weather. The established profile describes heat and drought tolerance, but regular watering supports vigorous growth and flowering. ## Maintenance Spent flowers do not need to be removed to maintain bloom. Trim trailing stems only when they exceed the available space or to refresh the planter; the plant naturally fills and spills as the season progresses.
