'Conga Dark Blue' Million Bells will bring a rich dark purple-blue to hanging baskets, container planters, borders, and any sunny spot you like in the garden. This series of calibrachoa tends to bloom a bit earlier than other varieties, and will keep on keeping on right up until freeze. More mounding than trailing, 'Conga Dark Blue' has a dark throat with yellow eye. For gardeners who don't have much space but want intense color, consider this glorious mini-petunia.
