Flowers are usually the central feature of the window box for most gardeners, and if your home’s façade is sunny, you can have a large range of blooming choices. Whether you prefer a substantial wooden trough or a series of hayrack planters, your sunny window box will draw attention throughout the growing season. Other trailing flowers that will spill handsomely over the edges of your sunny window box planter include trailing ivy-leafed pelargoniums, black-eyed susan vine, and euphorbia ‘Diamond Frost’. Intersperse your trailing flowers with trailing foliage plants like sweet potato vine or creeping jenny for textural interest.
