Calibrachoa formally known as Million Bells. Calibrachoa flowers look just like miniature petunias. Ideal for planting in hanging baskets and pots, these plants grow at an amazing rate, with a cascade of flowers soon tumbling over the side of hanging baskets and window boxes. Calibrachoa make strong, robust plants with dark green leaves and vivid flower colours looking bright even on dull days. They also tolerate cooler, damper conditions than some of the older Million Bells varieties.
