Bumble Bee Blue Calibrachoa (Calibrachoa hybrida ‘Balcanumlu’) stands out with bicolor blue petals that fade into a star-shaped yellow center. Its trailing, mounded habit reaches 10 to 15 inches tall and wide, bursting with blooms that continue throughout spring, summer, and even into autumn. The bright color contrast draws attention in mixed containers, hanging baskets, and garden beds. With strong branching and a profusion of large flowers, this mini petunia offers a showier display than many other calibrachoa varieties.

Its lightly cascading stems spill over pot edges, creating a brilliant waterfall of color, and its heat tolerance keeps the blooms performing in warmer conditions. While not fragrant, the flowers invite butterflies, bees, and hummingbirds, contributing to a pollinator-friendly space. Careful breeding has made it adaptable and low-maintenance, making it an easy choice for gardeners. Use it as an eye-catching border plant, mass it in sunny beds, or pair it with other calibrachoas for a bold color statement.

Bumble Bee Blue Calibrachoa Care

Plant in full sun to partial shade, ensuring at least six hours of daily light for the best flower production. Water deeply but allow the soil to dry slightly between waterings, as calibrachoa thrives in well-draining conditions. A weekly application of a water-soluble, balanced fertilizer supports steady growth and ongoing blooms. While it tolerates a range of soil pH levels, slightly acidic to neutral soils typically yield optimal results.

A light shearing in midsummer can encourage fresh blooms and help maintain a compact form. Pinch off spent flowers or trim back trailing stems if they become leggy, especially in containers. In colder climates, treat it as an annual and discard or compost the plants once the first frost arrives. Container-grown specimens can be brought indoors as a houseplant if given sufficient light, though it may not flower as heavily.

Bumble Bee Blue Calibrachoa Spacing

When planting in rows or for mass groundcover, position individual plants about 8 to 12 inches apart, allowing them room to spread. For single specimens or small groupings, leave approximately 10 to 15 inches of space on all sides to showcase their trailing habit. If opting for a container or hanging basket, choose one at least 10 to 12 inches in diameter so the roots have ample room to develop.
