Superbells® Blue Calibrachoa

Superbells® Blue is a mounding, trailing calibrachoa with deep blue-purple flowers. The [Proven Winners retail profile](https://provenwinnersdirect.com/products/superbells-blue-calibrachoa) lists a 6–12 inch height, 12–24 inch spread, spring-to-fall flowering, and USDA zones 9–11 for this named selection. ## Form and use Blue works well in hanging baskets, window boxes, and mixed containers, where its stems can spill over the rim. Plant it near a path or seating area to enjoy the small flowers up close. Calibrachoa is a tender perennial usually grown as a seasonal annual in cooler climates. ## Growing conditions Choose full sun to part sun and a fertile potting mix that drains freely. [NCSU Extension](https://plants.ces.ncsu.edu/plants/calibrachoa-x-hybrida/) recommends moist, organically rich soil with good drainage; [Illinois Extension](https://extension.illinois.edu/flowers/calibrachoa) advises regular watering and feeding, particularly in containers. Keep the mix evenly moist through active growth but avoid letting the pot stand in water. ## Maintenance Water before the plant wilts, checking baskets often in hot or windy weather. Feed according to label directions while flowering. The blooms are self-cleaning, so deadheading is not needed; lightly trim any leggy stems to restore an even shape.
