Superbells® Double Ruby Double Calibrachoa

Superbells® Double Ruby is a double-flowered calibrachoa with ruby-red blooms and a mounding, trailing habit. Proven Winners lists plants about 6–12 inches tall and 12–24 inches wide, flowering from spring through fall. The cascading stems suit hanging baskets, patio pots, and the edges of sunny mixed plantings. ## Form and flowering The layered red blooms provide the main ornamental feature against green foliage. This selection can fill a container while spilling over its rim; actual spread depends on growing conditions and container size. ## Growing conditions Provide full sun or part sun and fertile, moist but well-drained soil. Proven Winners lists USDA zones 9–11; calibrachoa is a tender perennial commonly grown as an annual in colder climates. Containers need regular moisture checks and drainage, and active plants benefit from regular feeding. Extension sources describe calibrachoa flowering through the warm season until frost.

Feed regularly while actively growing, especially in hanging baskets and pots. Routine deadheading is unnecessary; prune lightly if stems become untidy. Treat as a seasonal annual where it is not winter hardy.
