Calibrachoa

thumb|calibrachoa "million bells" in a hanging basket thumb|hybrid 'Superbells Strawberry Punch' Calibrachoa is a genus of plants in the Solanaceae (nightshade) family. They are evergreen short-lived perennials and subshrubs with a sprawling habit, with small petunia-type flowers. They are found across much the same region of South America as petunias, from southern Brazil across to Peru and Chile, inhabiting scrub and open grassland.

==Classification== Calibrachoa are closely related to 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. Petchoa is a hybrid genus derived from crossing the genetically similar Calibrachoa and Petunia.
