Calibrachoa, often called million bells or trailing petunia, boasts profuse amounts of dainty, petunia-like blooms from spring until frost. Winter hardy in Zones 9-11, it's grown as an annual everywhere else. Calibrachoa is a prolific bloomer, producing hundreds of 1" flowers in a range of colors -- violet, blue, pink, red, magenta, yellow, bronze, and white -- on trailing stems that look stunning in hanging baskets and containers, or in small areas as groundcovers.
