According to Steve Silk on FineGardening,com,'...I’ve come to realize there’s no mystery in making a scrumptious container planting as long as I follow a simple three-ingredient recipe. First and foremost is what I call a “thriller,” a centerpiece plant with star quality, something big, bold, and beautiful. Then I add a few spicy “fillers,” foliage or flowering plants that will complement but not overwhelm the main player. Finally, I add a savory splash of mischief, a “spiller” that just tumbles out of the pot. As long as I use each of those kinds of plants—in various proportions—and take care to balance colors and textures, I can create a pot with pizzazz.'
Allah SWT willing I will apply this principle for the flower containers on the front porch.
