Million Bells
Calibrachoa is a genus of plants in the Solanaceae (nightshade) family. They are weak evergreenperennials with a sprawling habit, and they have small Petunia-type flowers.
Calibrachoa are closely related to the Petunia. However on further examination it has been found that there are major differences in chromosomes and breeding behaviour between Calibrachoa and Petunias. The name Calibrachoa comes from Antonio de Caly Bracho, who was a Mexican professor of pharmacy.
Calibrachoa or trailing petunia is a tender perennial which produces flowers that look like small petunias. These are compact, mounded plants which grow 3-9” tall on mostly trailing stems. Sometimes commonly called million bells, these plants are prolific bloomers that produce hundreds of 1” wide flowers from spring to frost. Flower colors include shades of violet, blue, pink, red, magenta, yellow, bronze, and white.
