Add Charm with Window Boxes
What's planted: 'Aaron' white caladium, 'Key Lime Pie' heuchera, 'White Nancy' spotted dead nettle, holly fern, ivy, and light pink periwinkle
What's planted: Japanese iris is the thriller. White snapdragon, violet African daisy, red common geranium, and white 'Tidal Wave Silver' petunia are fillers. Pink and red ivy geraniums, dark red calibrachoa, and purple Lanai verbena are spillers.
Get the look: For an upscale window box (like the one above), have one custom made from rot-resistant wood, such as cedar. It will need painting and a metal liner inside to make it last. Check out less expensive alternatives at gardeners.com, kinsmangarden.com, plowhearth.com, and hooksandlattice.com, and see the Smith & Hawken collection at target.com.
What's planted: coral twinspur (diascia), blue Panola pansy, blue delphinium, blue edging lobelia, white common geranium, coral trailing petunia, and white 'Diamond Frost' euphorbia
One simple rule to make window boxes like these more interesting: Plant a thriller (something tall, such as a blooming geranium), a filler (something to add fullness, such as colorful caladium), and a spiller (something to trail over the sides, such as purple petunias).
What's planted: salmon pink geranium, 'Pink Beauty' caladium, and purple petunias
Winter is equally stellar when you know what to plant. Begin with a focal point, the one element that draws attention. In this window box, a tall pyramid-shaped boxwood serves as the anchor plant. To each side, a small, round boxwood repeats the texture and fills the container with substantial foliage. Accent the green with bright red nandina berries gathered from the yard.
What's planted: boxwoods, paperwhites, green-and-white flowering cabbages (in 4-inch pots), silvery dusty miller, white violas, green-and-white ivy, and red nandina berries
