Heliotrope and creeping jenny in pot. Haven't tried these together, but use creeping jenny in my pots and window boxes every year. My favorite color combination for my gardens is deep purple, vibrant pink and bright yellow.
A long planter chock-full of flowers and foliage substitutes for a window box on a porch railing. ‘Goldilocks’ creeping Jenny, ‘Burlesque’ pigeon berry, Madagascar dragon tree, calibrochoa and coleus create a lush mix of upright and trailing plants.
