Otherwise known as million bells, the calibrachoa is the quintessential bedding plant. Their small but bold blooms resemble a tiny petunia and bring instant color to your garden with little care. They are native to Brazil and Uruguay and are actually a member of the nightshade family. Water, fertilize and watch them thrive, no deadheading necessary! They love full to part sun and can grow 6-12 inches tall and trail 30 inches. Zone 9-11.
