Definition of "calibrachoa"

Annual geraniums and tobacco relatives like petunias, calibrachoas and nicotianas suffer most, but other flowers including osteospermums, mallows and chrysanthemums may also be attacked.

The most frequently detected virus of calibrachoas has been characterized recently, named calibrachoa mottle virus (CbMV) and has been tentatively assigned to the genus Carmovirus.

Closely related to petunias, calibrachoas are 3- to 9-inch-tall plants with trailing stems and a mounding habit.

Also, the 'Superbells' tend to be more vigorous than 'Million Bells' and other calibrachoa varieties.All calibrachoas have several shortcomings in differing degrees, depending on variety—they are generally short lived, providing a bold burst of color at the start of the season, but dwindling as the soil pH changes from acid to alkaline from fertilizing.
