How to Select the Best Window Box Plant Favorites
The secret to stunning window box displays is not just about picking pretty flowers. It's about finding plant varieties that thrive in your unique conditions and keeping them healthy all season long. Here's what to consider when choosing plants for your window boxes:
Assess Your Light Exposure
Is your window box in full sun, partial shade, or deep shade? Many common window box plant favorites, such as petunias and geraniums, thrive in 6+ hours of sun, while others like impatiens, ferns, and begonias shine in shade.
- Full Sun (6+ hours): Petunias, geraniums, verbena, marigolds, million bells
- Part Shade (3-6 hours): Lobelia, fuchsias, begonias, coleus
- Full Shade (<3 hours): Impatiens, ferns, English ivy, heuchera
Consider Your Climate and Hardiness Zone
Your local climate and the hardiness zone will determine which plants can be left outside year-round and which must be treated as annuals or brought inside for winter. Always check each flower or greenery's requirements when picking your window box flower favorites.
Choose a Theme or Color Palette
Whether you love bold contrasts, soft pastels, or a rainbow explosion, selecting a window box color scheme creates cohesiveness and extra curb appeal:
- Romantic Pastels: Soft pinks, lavender, blues, and silvers
- Vibrant Tropicals: Oranges, reds, hot pinks, and chartreuse foliage
- Monochrome Magic: Shades of one color, such as all white, for nighttime drama
- Seasonal Swaps: Spring bulbs, summer annuals, autumn mums, winter evergreens
Top Window Box Plant Favorites for Every Home
Let's explore some of the most popular and reliable window box plants that gardeners and designers love for their beauty, adaptability, and easy care. Mix and match these favorites for a container garden that's both eye-catching and low-maintenance.
1. Geraniums
Geraniums (Pelargonium) are beloved for their bright, cheerful blooms and easy-going nature. Their rounded blossoms and blue-green leaves make them a classic choice for window boxes. With abundant colors from pure white to hot pink and vivid scarlet, geraniums provide all-summer impact.
- Light Needs: Full sun
- Watering: Allow soil to dry out slightly between waterings
- Bonus: Scented-leaf varieties offer extra fragrance
2. Petunias
If you crave overflowing cascades of color, petunias are a sure bet. Trailing and mounding varieties fill window boxes with trumpet-shaped flowers in every hue imaginable. Look for surfinia or wave petunias for an effortless 'waterfall' effect.
- Light Needs: Full sun
- Watering: Keep evenly moist; avoid waterlogging
- Tip: Pinch back after initial blooms to encourage reblooming
3. Impatiens
For those tricky shady spots, impatiens are an unbeatable window box flower favorite. Their prolific blossoms thrive even where little else will grow, filling window boxes with vibrant pinks, purples, reds, and pure white. Try double-flowered varieties for a "mini-rose" effect!
- Light Needs: Shade to part shade
- Watering: Consistently moist, but not soggy
4. Ivy Geranium
With glossy leaves and trailing blooms, ivy geraniums (Pelargonium peltatum) are perfect for dramatic spillover in window boxes. The flowers are less dense than standard geraniums but offer non-stop color and a finer, more elegant appearance.
- Light Needs: Full sun to part shade
- Watering: Allow to dry slightly between waterings
5. Calibrachoa (Million Bells)
Nicknamed "mini petunias," calibrachoa produce tiny bell-shaped flowers in dazzling abundance. Calibrachoa are low-maintenance, bloom from spring to frost, and come in a spectrum from pastel yellow to deep violet, creating a certain wow-factor in your window boxes.
- Light Needs: Full sun (can tolerate part sun)
- Watering: Keep evenly moist
- Bonus: Self-cleaning (no deadheading necessary!)
6. Trailing Lobelia
Lobelia is a striking window box plant favorite for its cascading habit and vivid blue, purple, or white flowers. Use it as a "spiller" to soften box edges and mix with upright "thriller" plants for a balanced look.
- Light Needs: Sun to part shade
- Watering: Keep soil steadily moist
- Best Use: In cooler climates or spring/fall displays
7. Begonias
With spectacular foliage and long-lasting blooms, begonias excel in shaded or low-light window boxes. There are tuberous, wax, and rex begonias to choose from--mix them for texture and drama.
- Light Needs: Shade to part shade
- Watering: Water when top inch of soil feels dry
- Tip: Excellent heat and humidity tolerance
8. Sweet Alyssum
For honey-sweet fragrance and a carpet of tiny white, pink, or purple blooms, sweet alyssum is a cottage garden staple. Its low mounding habit makes it an ideal window box edging plant that also attracts pollinators.
- Light Needs: Sun to partial shade
- Watering: Tolerant of drought but happier with regular water
- Bonus: Excellent in spring or fall; less vibrant in mid-summer heat
9. Fuchsia
The dangling, bicolor flowers of fuchsias offer an exotic touch to shady window boxes. Their unique shape and color combinations--magenta, purple, red, and white--make them showstoppers for north- or east-facing windows.
- Light Needs: Part shade to shade
- Watering: Evenly moist
- Season: Best in spring through early fall
10. Ornamental Grasses
Don't underestimate the power of foliage! Adding trailing or upright ornamental grasses--like carex, blue fescue, or fiber optic grass--brings movement, texture, and sophisticated structure to your window box plantings.
- Light Needs: Depends on variety (most prefer sun)
- Watering: Drought-tolerant options available
- Best Combinations: Use with bold bloomers for contrast

Designing Your Perfect Window Box Display
Designing captivating window box plant arrangements is easy with the "Thriller, Filler, Spiller" method:
- Thriller: Upright or showy plants (such as geraniums or upright begonias) for height and drama
- Filler: Mounding or bushy plants (petunias, million bells, or sweet alyssum) to fill out the middle
- Spiller: Trailing varieties (ivy, lobelia, vinca vine) for cascades over the box edges
Vary the foliage size, shape, and color to create texture, depth, and visual interest. Place the tallest plants towards the back or center (depending on box orientation) and work forwards with shorter, trailing plants.
Tips for Arranging Window Box Plants:
- Plant densely for a lush look, but allow space for growth
- Repeat colors or foliage types for unity throughout your arrangement
- Mix edible herbs and flowers for multi-purpose beauty
- Don't forget fragrance--add lavender, alyssum, or scented geraniums
- Switch out plants seasonally for fresh looks year-round
