The large, bright gold flowers from Bidens Goldilocks Rocks work wonderfully with the joyfully cascading and abundant small petunia-like flowers of the Calibrachoa, with their soft-yellow centers overlaid with purple on white splashes. Whiteout Verbena features pure white flower clusters and the airy, white blooms of White Gaura give that plant its very apt name, the Butterfly plant, dancing as they do! This is a spectacular combination for a large planter.
