Calibrachoa

Calibrachoa is a genus of flowering plants related to petunias, and many cultivated forms are called million bells. Extension profiles describe Calibrachoa × hybrida as compact, vigorous and useful in baskets or as groundcover; the [Illinois profile](https://extension.illinois.edu/flowers/calibrachoa) and [North Carolina Extension profile](https://plants.ces.ncsu.edu/plants/calibrachoa-x-hybrida/) cover its growing conditions and seasonal flowers. Calibrachoa belongs to the Solanaceae family, as shown in the [RHS botanical profile](https://www.rhs.org.uk/plants/347659/calibrachoa-million-bells-mounding-red-improved/details). ## Garden use Use cultivated calibrachoa in containers, hanging baskets, window boxes and sunny bed edges. The North Carolina Extension profile describes a low, spreading hybrid with small trumpet-shaped blooms, while Illinois Extension also lists basket and groundcover uses. Habit and mature size vary among species and named selections, so check the specific plant label when spacing a mixed planting. ## Light and soil Choose a bright site with full sun and provide fertile, moist but well-drained soil. Illinois Extension recommends feeding regularly, especially for plants in containers, where the potting mix dries faster than garden soil. Avoid leaving roots in standing water. ## Seasonal interest In Illinois, the extension profile lists flowering from May through October and describes calibrachoa as a tender annual. In colder regions it is usually enjoyed as a warm-season container or bedding plant until frost; flowering dates vary with climate and selection. ## Maintenance Check container moisture often during warm or windy weather and feed according to the fertilizer label. Pinch or trim loose stems to keep a compact outline. North Carolina Extension notes that routine removal of spent flowers is not needed for the hybrid profile it covers.
