Calibrachoas (also known as million bells, trailing petunias or superbells) are tender perennials grown as annuals in the UK. They have masses of pretty, bell-like flowers that look like mini petunias and come in a range of colours, including lavender, blue, pink, red, magenta, yellow, orange, coral and white
Calibrachoas are best planted in containers –they look lovely tumbling over the sides of hanging baskets, pots or window boxes in summer. Buy them as plug plants in early spring or as garden-ready plants from late spring to summer. Keep well watered and feed every couple of weeks with a high potash feed. Compost the plants at the end of the season.
Calibrachoas need a sheltered spot, in sun or very light shade. They will grow in the ground, but it's best to grow them in containers or hanging baskets with other summer annuals, letting them trail over the edge.
