Add yellow to the primary mix with daisies. This suits any kind of 24-inch container, from hanging basket to window box. Cluster the plants in their own areas of the container, using three 4-inch pots of each plant: Marguerite Daisy Molimba® Hello White, Lobelia Laguna™ Compact Blue with Eye, Nemesia Sunsatia® Cranberry and Golden Leaf Sage Icterina.
