They are suitable for container gardening and hanging baskets and will attract hummingbirds. They can be propagated from tip cuttings, but are frequently grown as half-hardy annuals. Plant in a free-draining soil and water only when the soil is almost dry. The plants can tolerate light frost and thrive in sun or semi-shade. Some Calibrachoa are cultivated as ornamental plants, popularly known as "Million Bells". This structure is due to walls perpendicular to the seed surface, which are straight in all species. The color of the crown can be purple, red, pink or whitish. The crown is funnel-shaped, only in Calibrachoa pygmaea it is salver-shaped, bulbous and tapered towards the tip. The calyx has five or ten ribs, it is usually lobed to about the middle, the lobes are usually narrowed towards the top. The flowers are usually zygomorphic, the bud cover is reciprocal in most species, the only exception is Calibrachoa pygmaea in both cases. The inflorescences are monochasic and have oppositely standing, foliage-like bracts. The leaves are ovate, elliptic, reverse ovate or linear its edge is flat or rolled back. Ĭalibrachoa was named by Vicente Cervantes after Antonio de la Cal y Bracho, a 19th-century Mexican botanist and pharmacologist.Ĭalibrachoa are small shrubs or herbaceous plants with woody shoot axis that grow annual or perennial. Petchoa is a hybrid genus derived from crossing the genetically similar Calibrachoa and Petunia. However, on further examination it has been found that there are major differences in chromosomes, corresponding to external differences and fertilization factors that distinguished the two genera. Calibrachoa are closely related to Petunia.
