Superbells® Plum Calibrachoa

Superbells® Plum is a flowering Calibrachoa selected for a long display of plum-purple blooms and cascading growth. Proven Winners recommends it for containers, where its stems can spill over basket and planter edges. The cultivar is typically grown as a warm-season annual. ## Form and season Proven Winners describes this cultivar as mounding and trailing, with flowering from spring through fall and a mature range of 6–12 inches tall by 12–24 inches wide ([cultivar profile](https://www.provenwinners.com/plants/calibrachoa/superbells-plum-ii-calibrachoa)). Its flowers continue from planting until hard frost under suitable conditions. The compact height and broader spread make it useful at the edge of mixed containers and hanging baskets. The plant ID matches the breeder’s cultivar code BBCAL76001. Proven Winners currently styles that code as Plum II; older catalogs list Superbells Plum, so the existing display name is preserved. Its [official variety list](https://www.provenwinners.com/sites/provenwinners.com/files/pdf/2024-25_proven_winners_protected_plant_varieties.pdf) records U.S. Plant Patent 29,872 and Canadian plant protection 6,054. ## Siting and care Grow in full sun to part sun. Calibrachoa roots are sensitive to constantly wet soil, so a free-draining container mix makes moisture easier to manage. Water when the surface begins to dry, but do not let the plant wilt severely. Feed regularly through the growing season; check the breeder’s guidance for application rates and timing. In a garden bed, use only a well-drained site. ## Maintenance Spent flowers do not need routine deadheading. Trim the longest stems around midsummer if the plant becomes uneven, removing no more than about one fifth at a time, then resume regular feeding to encourage fresh growth. Remove damaged material and keep containers draining freely.
