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.
pinner says overflowing.some of my faves' petunias and sweet potato vine. I plant the green and the purple vine each summer, take cuttings before the first freeze and keep them growing in a qt. jar of water thru winter in my kitchen window.
