1. Purple Shamrock (Oxalis triangularis)

This unusual window box plant features vibrant, triangular leaves in a deep purple shade that fold up at night. Not only is the foliage spectacular, but it also produces clusters of dainty, light-pink or white flowers. Oxalis triangularis thrives in partial shade, making it perfect for windows that receive filtered sunlight.

2. Silver Falls (Dichondra argentea)

Add a touch of shimmering elegance with Silver Falls. Its trailing, silvery foliage cascades gracefully, creating a striking contrast against darker plants.

Out-of-the-Ordinary Flowers for a Showstopping Window Box

1. Nemesia 'Midnight Blue'

This cultivar is a true showstopper thanks to its intensely deep blue, velvet-like petals. It blooms profusely from spring through fall, with a sweet scent that will greet you each time you open your window. Pair it with lighter shades or trailing foliage for stunning contrast.

2. Kangaroo Paw (Anigozanthos)

Native to Australia, Kangaroo Paw boasts fuzzy, tubular flowers in shades of red, yellow, and green. Its upright habit and unique texture create an exotic vibe when tucked into a sunny window box. It prefers well-draining soil and regular watering during dry spells.

For airy height and a whimsical touch, try the Spider Flower. Its spidery blossoms come in white, pink, or purple, floating above tall, sturdy stems. Cleome tolerates sun and dry conditions, making it a resilient addition to your unique window box arrangement.

Succulents and Cacti: Low-Water Wonders

Succulents and cacti bring an intriguing architectural element to any window box, offering unique shapes and textures while thriving on minimal water. Consider mixing several types for a modern, desert-inspired display.

String of Pearls (Senecio rowleyanus): This trailing succulent features bead-like foliage that spills dramatically over the edge of containers.
Hens and Chicks (Sempervivum): Hardy and easy to grow, these rosettes come in an array of colors from green to deep burgundy.
Bunny Ear Cactus (Opuntia microdasys): Unique for its pad-shaped stems and soft, yellow tufts, this cactus adds a touch of whimsy.
Cobweb Houseleek (Sempervivum arachnoideum): Named for its spiderweb-like filaments, offering a quirky twist on classic succulents.

Edible Yet Decorative: Adding Flavor and Flair

Who says unusual window box plants can't be edible as well as ornamental? Grow the following selections for something beautiful and delicious:

Purple Basil (Ocimum basilicum 'Purpurascens'): Deep-purple leaves with a mild basil flavor. Stunning next to silver or lime-green plants.
Pineapple Sage (Salvia elegans): Spicy-sweet foliage and brilliant red flowers that attract hummingbirds.
Nasturtiums (Tropaeolum majus): Both the round leaves and vibrant blooms are edible, providing a peppery flavor for salads.
Society Garlic (Tulbaghia violacea): Grass-like leaves and lilac flowers with a mild garlic scent. Edible flowers and foliage add a twist to recipes.

Trailing and Dramatic: Plants with Cascading Appeal

1. Black-Eyed Susan Vine (Thunbergia alata)

This unique vine produces bright blooms in shades of orange, white, or yellow, each with a bold black center. Trailing stems make it perfect for window boxes, where it can drape elegantly over the edge, adding vertical interest.

2. Million Bells (Calibrachoa)

Although these resemble miniature petunias, Calibrachoa flowers come in far more unusual colors, ranging from neon pink to blue and exotic bronze. They're tough, prolific bloomers that spill over the sides of your arrangement, creating a cascading waterfall of color.

3. Sweet Potato Vine (Ipomoea batatas)

Not just an edible crop, ornamental sweet potato vine features deeply lobed leaves that come in jet black, chartreuse, or variegated patterns. Its lush, trailing stems can rapidly soften the edges of your window box with dramatic, flowing foliage.

Unusual Perennials for Lasting Interest

1. Heuchera (Coral Bells)

Heuchera's ruffled leaves vary from peachy-orange to metallic silver to almost black. Compact and shade-tolerant, they create year-round color in containers and contrast beautifully with bolder flowers and trailing greenery.

2. Hellebore (Lenten Rose)

Blooming in late winter or early spring, Hellebores grace your window box with unique, nodding flowers in hues from green to deep plum. Their leathery foliage looks good all year, and they're remarkably hardy.

3. Japanese Painted Fern (Athyrium niponicum)

This fern's silvery, purple-tinged fronds are both delicate and dramatic. Consider pairing with solid green plants for an artistic and unique window box arrangement.

Rare Climbing Plants for Vertical Drama

Polka Dot Plant (Hypoestes phyllostachya): Covered in pink, red, or white speckling, this cheerful plant adds whimsy to your unique window box.

Tips for Designing Your Unique Window Box Arrangement

Layering uncommon plants requires a bit of planning. Here are some top tips for arranging your unusual window box garden:

Mix textures and forms: Combine trailing plants with upright growers, and pair bold-flowered species with intricate foliage for dynamic displays.
Mind light requirements: Group together plants with similar sunlight needs--some exotic species prefer shade, while others demand full sun.
Consider color schemes: Use a color wheel to create contrasts, or keep to one palette for harmony.
Include some evergreens: For year-round interest, blend in evergreen or perennial plants with showy seasonal options.
Water and soil: Many unusual plants need excellent drainage, so use a loose, peat-free compost and check that your window box has adequate drainage holes.

How to Care for Unique and Unusual Plants in a Window Box

Caring for exotic varieties in containers differs slightly from standard annuals:

Check for temperature tolerance, especially if your area experiences harsh winters--bring tender plants indoors or choose cold-hardy varieties.
Feed regularly. Unusual plants can be heavy feeders. A weekly dose of balanced, water-soluble fertilizer supports lush growth and more blooms.
Keep an eye on water. Even drought-tolerant succulents and cacti need regular (but not excessive) water during the hottest months.
Prune as needed to shape growth, encourage new blooms, and maintain your arrangement's balance.
