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.
Wall color is Pale Oak Benjamin Moore. Pale Oak is a light warmer greige (gray/beige) that leans just a tad warmer than traditional greiges. In spaces with a lot of natural light (like this space below), Pale Oak will look more of a warm off white.
