• Size: Deeper boxes allow for a larger root system and a wider variety of plants.
• Material: Options range from classic wood to lightweight plastic or self-watering fiberglass.
• Drainage: Boxes must have proper drainage holes to prevent root rot.
• Exposure: Evaluate the amount of sun and wind the box will receive (this influences plant choice).

The real magic happens with plant selection. The most attractive window boxes feature a mix of colors, shapes, heights, and textures. The tried-and-true mantra "thriller, filler, spiller" describes the technique of combining upright, mounding, and trailing plants for lush, eye-catching displays.

We've compiled a list of the best plants for window boxes--categorized by sunlight requirements and visual effect.

Design Principles for Stunning Window Box Displays

A visually-arresting window box involves more than just picking your favorite flowers. Blend color, form, and texture for stunning impact.

The "Thriller, Filler, Spiller" Formula

• Thriller: Upright, attention-grabbing plants (like Angelonia, Salvia, Ornamental Grasses).
• Filler: Mounding or rounded plants that add mass (Geraniums, Begonias, Alyssum).
• Spiller: Trailing choices that cascade over the edge (Petunias, Ivy, Creeping Jenny).

Tip: Repetition of color and form creates harmony, while contrasting foliage (such as combining feathery ferns with bold-leafed begonias) adds drama.

Playing with Color and Seasonality

• Mono-color: Cools and simplifies with (all white or all purple).
• Complementary colors: Bold and energetic (pairing purple with yellow, red with green).
• Seasonal swaps: Consider spring bulbs (daffodils, tulips), summer annuals, autumn pansies, and winter evergreens.

Tips for Planting and Maintaining Your Window Boxes

No matter which plant varieties for window boxes you choose, proper setup and ongoing care are vital for success. Here's how to get your display started:

Planting Guide

1. Prepare the container: Check for drainage and add a layer of lightweight gravel or broken clay to the bottom.
2. Use high-quality potting soil: Choose a mix designed for containers--it holds moisture and nutrients.
3. Arrange your plants: Start with "thrillers" in the back (if the box faces outward) or center (if viewed both sides), then add fillers and spillers.
4. Spacing: Don't overcrowd--plants need room to grow and airflow for health.
5. Water thoroughly: After planting, give the box a generous soak.

Maintenance and Care Tips

• Water consistently, especially in hot and windy conditions. Self-watering boxes are helpful for busy schedules.
• Fertilize regularly with a balanced liquid feed to encourage lush growth and continuous flowers.
• Deadhead spent blooms and trim leggy growth to keep the display tidy and productive.
• Keep an eye out for pests and diseases. Remove affected foliage and treat promptly if issues arise.
• Change up your window boxes with the seasons for year-round color.
