The leaves of 'Carnival Black Olive' Coral Bells have a roundness and coloring that does indeed remind one of black olives. Slightly lobed and rounded upward, the leaves are purplish-black with green undertones, while the undersides are more wine-colored. White flowers bloom in late spring to summer that are fully appreciated by hummingbirds and bees alike. A terrific option for woodland gardens, container planters, borders, and hanging baskets, 'Carnival Black Olive' will provide year-round interest.
