Best Foliage & Ornamental Plants

Coleus

Bright, colorful foliage makes coleus a standout in window boxes. Many varieties tolerate both sun and shade, making them extremely versatile.

Ivy

Ivy provides trailing movement and classic greenery. It’s hardy, tolerant of cooler conditions, and pairs well with flowering plants.

Ipomoea (Sweet Potato Vine)

Known for trailing foliage in lime green or deep purple tones, ipomoea adds movement and contrast to window box arrangements.

Dusty Miller

Silver-gray foliage adds contrast and works beautifully with both modern and traditional homes.

Ornamental Grasses

Low-maintenance and architectural, ornamental grasses provide height and texture while tolerating varied conditions.

Herbs & Edible Plants for Window Boxes

Basil

Thrives in full sun and warm weather. Regular harvesting keeps plants productive and encourages fresh growth.

Tomatoes (Compact Varieties)

Small cherry or patio tomatoes grow well in deeper window boxes with strong sunlight and consistent watering.

Peppers

Compact chili and ornamental peppers provide color and edible harvests throughout the season.

Mint

Fragrant and fast growing. Mint is best grown in containers like window boxes to keep it contained.

Chives

Cold-tolerant and perennial in many zones, chives provide both flavor and soft seasonal blooms.

Planting tip: Use deeper window boxes for edibles and herbs so roots have enough space to grow.

Why Planter Quality Matters

Healthy plants start with a well-built planter. Durable materials help regulate moisture and support long-term planting success.

Material Why it Works
Copper Timeless look that develops natural patina
Stainless Steel Modern, durable, corrosion resistant

Why These Plants Thrive (When the Planter + Placement Are Right)

Window boxes are small spaces with big exposure — sun, wind, and drying cycles happen faster at window level. Choosing plants that match your light and pairing them with a durable planter makes your display last longer and look more “finished.”

  • Match plants to exposure: use shade-tolerant foliage where light is limited, and full-sun herbs/edibles where you get 6+ hours.
  • Use a balanced layout: the thriller–filler–spiller method creates height, fullness, and trailing movement in a clean, designer look.
  • Start with quality construction: stable, outdoor-ready materials support drainage and long-term performance season after season.

Frequently Asked Questions

Can I mix flowers, herbs, and foliage in one window box?
Yes — it’s one of the easiest ways to create a rich, layered look. Just group plants with similar sun and watering needs so they thrive together.
What plants are best for shade window boxes?
Shade-friendly choices include coleus, ivy, and other foliage-forward plants that offer color and texture even without strong sunlight.
Do edible plants need a deeper window box?
Usually, yes. Herbs and compact vegetables often perform best with extra soil volume to support roots and even moisture — especially in full sun.
What’s the easiest way to make a window box look “designer”?
Use the thriller–filler–spiller formula: one taller focal plant for height, mid-height plants for fullness, and trailing plants to soften edges and add movement.
How do I keep window box plantings looking good all season?
Check moisture regularly, trim or pinch back fast growers, and refresh tired plants seasonally. Consistent care matters more in window boxes because they dry out faster than garden beds.
