Top Must-Have Window Box Plants for Every Home
Our list covers a vibrant array of window planter plants, from sun-loving stunners to shade-tolerant beauties, and includes trailing accents and edible herbs. Mix and match these favorites for eye-catching, healthy window box displays!
1. Petunias -- The Classic, Colorful Favorite
Petunias are a tried-and-true staple for sunny window boxes. Their abundance of trumpet-shaped blooms comes in dazzling hues, making them a great option for instantly brightening your window sills. Petunias flourish in direct sunlight and well-draining soil. Regular deadheading will keep the blooms coming all season long.
- Sun Requirement: Full sun
- Color Varieties: White, pink, purple, blue, and bi-color
- Bonus Tip: Mix wave petunias for cascading effects
2. Geraniums -- Timeless Charm
The vibrant, cheerful blossoms of geraniums have made them one of the best plants for window boxes. With lush foliage and big flowers, geraniums tolerate heat well and, when deadheaded, bloom continuously from spring to frost.
- Best for: Sunny or partially sunny locations
- Classic Choice: Pair red geraniums with trailing ivy for a striking contrast
- Popular Types: Zonal, ivy-leaf, and scented geraniums
3. Begonias -- Shade-Loving and Spectacular
If your window box receives little sunlight, don't worry! Begonias are shade specialists, thriving in low-light conditions and available in many shapes and vibrant colors. Their waxy leaves and unique flower forms create abundant visual interest all season.
- Sun Requirement: Partial sun to full shade
- Watering: Keep soil evenly moist, but never soggy
- Foliage: Some varieties offer colorful or patterned leaves
4. Sweet Alyssum -- Fragrant Cascades
Sweet Alyssum is admired not just for its delicate clusters of tiny white, pink, or purple blossoms, but for its intoxicating honey fragrance. This trailing plant gently spills over the edges of window boxes, softening hard lines and attracting pollinators like bees and butterflies.
- Sun Requirement: Full sun to partial shade
- Highlight: Prolific spring and fall blossomer
- Care: Trim to rejuvenate after flowering flushes
5. Ivy and Trailing Vines -- Elegant Greenery
Add instant sophistication with ivy or trailing vines like trailing lobelia and creeping Jenny. These plants tumble gracefully over the window box's edge, providing lush texture throughout the growing season. They're excellent for both traditional and modern design schemes.
- Sun Requirement: Varies depending on the variety
- Bonus: Vines combine beautifully with upright or mounding flowers
6. Herbs -- Delicious and Decorative
Make your window planter boxes practical by incorporating herbs! Basil, thyme, oregano, parsley, and chives are easy to grow and provide fresh ingredients for your kitchen while adding texture and fragrance to your display.
- Sun Requirement: Most culinary herbs require full sun
- Maintenance: Regular trimming encourages bushier growth
- Arrangement Tip: Alternate herbal greenery with bright flowers for contrast
7. Calibrachoa -- Mini Petunia Magic
Calibrachoa, also called "Million Bells," produces dozens of tiny, bell-shaped flowers in colors ranging from neon pink and deep purple to sunny yellow and orange. These blooms spill artistically over the window box and attract hummingbirds and butterflies.
- Sun Requirement: Full sun
- Care: Provide well-draining soil and feed regularly for best results
- Benefit: No deadheading required for continuous bloom
8. Pansies and Violas -- Cool-Weather Wonders
Embrace the cool seasons with pansies and violas. Their velvety petals and "faces" bring color to windows during fall and early spring, providing valuable blooms when little else flowers. Swap in warm-season favorites as temperatures climb.
- Ideal for: Early spring and fall windows
- Color Range: Almost every color imaginable
9. Succulents -- Low-Maintenance and Modern
For a contemporary look (and minimal upkeep), consider a succulent-themed window box. Species such as sedum, echeveria, and hens-and-chicks are drought-tolerant, sculptural, and perfect for sunny exposures.
- Sun Requirement: Full sun to light shade
- Water: Sparingly; allow soil to dry completely between waterings
- Design Tip: Mix different leaf shapes and shades for extra impact
10. Ferns and Heucheras -- Elegant Shade Solutions
If your window faces north or sits in permanent shade, you can still enjoy beautiful greenery. Consider ferns and heucheras (coral bells) for their colorful foliage and delicate textures. They thrive without direct sunlight and provide long-lasting appeal.
- Sun Requirement: Shade to partial shade
- Longevity: Perennials in many climates
Designing a Show-Stopping Window Box
When planning your window planter display, think beyond individual plants. Combine contrasting textures, heights, and colors for extra curb appeal. Try the thriller-filler-spiller formula:
- Thriller: Upright plants as a focal point (e.g., geraniums, salvia)
- Filler: Medium-height mounding plants to fill in gaps (e.g., begonias, calibrachoa, herbs)
- Spiller: Trailing plants to cascade over the edges (e.g., sweet alyssum, ivy, creeping Jenny)
Helpful Design Tips:
- Stick to three to five plant varieties for a harmonious look
- Repeat colors or foliage in nearby boxes for unity
- Vary bloom times for a long-lasting display
- Use a lightweight, high-quality potting mix to prevent root rot
How to Grow and Care for Window Box Plants
Window box gardening is made easier by following these simple guidelines to keep your arrangements lush and vibrant:
1. Choosing the Right Container
- Select a window box that's at least 6-8 inches deep and wide enough for root growth
- Opt for materials such as wood, resin, or metal, ensuring drainage holes are present
- Add a layer of gravel or pottery shards at the base to aid drainage
2. Using a Suitable Potting Mix
- Use a high-quality, light potting soil rather than garden dirt
- Consider a mix with slow-release fertilizer for continuous feeding
- To boost water retention, mix in some peat moss or coir
3. Watering and Fertilizing
- Window boxes dry out quickly, especially in sun and wind; check soil moisture daily
- Water deeply, allowing excess to drain - avoid letting plants sit in water
- Feed with a balanced liquid fertilizer every 2-4 weeks, depending on plant needs
4. Pruning and Deadheading
- Remove faded blooms and yellowing leaves regularly
- Pinch back herbs and annuals to encourage bushier growth
- Trim trailing vines as needed to prevent overgrowth
5. Protection in Bad Weather
- Move boxes indoors or to sheltered spots during extreme heat or storms
- Mulch soil surface to help retain moisture and regulate root temperature
