15 Gorgeous Window Field Flower Concepts

Window boxes enchant with the seasonal delights of the garden. They bring vertical interest to unite home and landscape and emphasize or soften features. Reminiscent of European villages, these displays exude charm and natural connection. They also serve a variety of purposes, even in ancient Rome, where city dwellers without gardens used them to grow culinary and medicinal plants. 

Use window boxes in their intended spaces – beneath windows – or along a fence line, on a blank wall, balcony, porch railing, etc. Design them as you would any container, with focal point specimens, filler plants, and trailing varieties. Use colors from your garden, home, or those that inspire you. 

The beauty of window boxes is their ability to enliven and change. Evergreens and perennials flourish year-round, while annuals bring a diversity of color and form. They are a feast for the eyes from the inside looking out to the garden, and fragrance, too, is a bonus on those open-window days. 

When planting a window box, provide drainage holes and a well-draining potting mix. Follow sun and shade recommendations and combine plants with similar cultural requirements. Water consistently, especially during dry periods, as these small planters dry out more quickly than in-ground plantings.

Each flower is comprised of velvety petals, forming rounded umbels that contrast beautifully against the plant's lush, green foliage. Hydrangeas with delicate white inflorescences bloom in the flowerbed by the window.Boost cheer with vibrant, versatile geraniums.

Geraniums are among the most popular blooms for window boxes and planters because of their vibrant blooms and rich foliage. Their rounded, ruffly leaves are true green, mottled, or variegated. Color-saturated flower clusters rise above leafy branches throughout the warm season. 

Common garden geraniums, scented geraniums, and ivy-leaf geraniums feature distinct leaves, flowers, and forms. From cherry red blooms to lemony scented leaves to trailing stems, geranium varieties serve many garden situations. 

Geraniums bring texture and vibrancy to the flower box display. They make a striking statement on their own and pair beautifully with an endless combination of plantings. Use them as bold filler and embellish with trailing plants like variegated ivy, dichondra, creeping jenny, calibrachoa, and vinca.

Provide geraniums with at least four to six hours of sunlight. In hot climates, offer protection from direct afternoon sun. Geraniums thrive with regular water in well-drained soils, allowing the soil to dry out slightly between waterings. Pinch off spent blooms to encourage more flowers and a full, leafy plant.

Impatiens are known for their abundance of vibrant blossoms that adorn their lush, green foliage. These flowers come in a range of colors including pink and white, with delicate speckles at their centers. With their five-petaled, trumpet-shaped blooms and glossy, succulent-like leaves, impatiens create a profusion of color and texture.Grace your window box with the vibrant hues of impatiens.

Like geraniums, impatiens are among the most popular annuals. They flower profusely in a myriad of colors, from baby pink to neon magenta. Impatiens perform well in partial to full shade, with different species and hybrids tolerating more sunlight.

New Guinea impatiens, Impatiens hawkeri, feature large flowers with elongated leaves, often deep in color with a metallic sheen. They tolerate the sun better than the tuberous I. walleriana, the sweet, shade-loving garden classic, and are more resistant to mildew diseases.

For a sun-loving impatiens hybrid, look to the SunpatiensⓇ series. Sunpatiens handle full sun, bringing the pop of the impatiens’ colorful bloom to the sunny window. All impatiens require organically rich soils and consistent moisture throughout the summer. 

In our window box example, blended pastels and complementary shades incorporate blush pink impatiens to flank a central bright pink impatiens focal point. Chartreuse heuchera brings high contrast, and trailing ‘Silver Falls’ dichondra and lavender calibrachoa cool the display. Rose angelonia gives spiky, upright interest in the backdrop.

Snapdragons, characterized by their tall spikes adorned with clusters of deep pink, tube-shaped blossoms, feature lance-shaped leaves arranged densely along sturdy stems. The blooms, resembling small, dragon-like faces.
Consider vibrant snapdragons as the centerpiece.

With their range of flower heights and colors, snapdragons are perfect for window boxes. Use them as the “thriller” features of the arrangements – tall, upright spikes of intense color – and surround them with low-growing mounding and trailing plants.

Use bold snapdragons with coral and purple nemesia, ornamental grasses, and dusty miller. Blue and purple ageratum or bacopa soften the mix. Trailing plants like ivy, creeping jenny, and sweet potato vine make a vibrant backdrop. Snaps are beautiful among pansies and violas with evergreens, too.

Snapdragons thrive in the sun in moist, well-drained soils. Remove spent blooms to promote flowering. In mild climates, snaps bloom all winter long.  In colder climates, snapdragons bloom in spring, summer, and fall.

Its vibrant, star-shaped flowers bloom profusely in clusters atop the foliage. These flowers are purple in color with white centers.Add drama with trailing annual vinca blooms.

Annual vinca brings abundant color with low maintenance needs. Blooms range from pastel to bold hues against an attractive backdrop of deep green, glossy foliage. Flower “eyes” brighten bloom centers in contrasting colors, often clear white, yellow, or pink.

Annual vinca makes a good filler specimen if your window box receives lots of sunlight in high heat conditions. Trailing varieties create lovely accents and spill over the sides. Pair vinca with any sun-loving annuals and perennials for a summer show. 

Annual vinca differs from perennial vinca, Vinca minor, which is also a pretty trailing plant in window boxes where it stays contained. Variegated foliage and deep periwinkle blooms are a sweet accent in partial shade containers.

Annual vinca thrives in hot and dry conditions in well-draining soils, though container plants need more regular water since they dry out more quickly. At planting time, fertilize vinca with a balanced, organic application. A single application lasts all season, as vinca doesn’t require many added nutrients.


Window boxes of begonias and caladiums. Begonias showcase large asymmetrical foliage of a glossy green color.
