Supertunia Mini Vista petunias are mounded, but will also spill over the edges of containers. They are great container plants and will function as both spillers and fillers in combination planters. They are incredibly good landscape plants, best used at the front of beds. They are very densely branched plants. They have small to very small flowers. They are a great substitute for Calibrachoa in landscapes without excellent drainage – Calibrachoa requires excellent drainage to thrive, while petunias are much more forgiving.
