If you’re looking for a simple way to boost your home’s curb appeal and enhance the beauty of your backyard, ornamental grasses are the perfect solution.

Known for their low-maintenance care, stunning textures, and graceful movement, ornamental grasses add year-round interest to your outdoor spaces.

Whether you prefer bold, colorful foliage, soft feathery plumes, or structured, architectural forms, there’s an ornamental grass to suit every style.

One of the easiest ways to incorporate these hardy plants into your landscape is by growing them in containers.

This method offers flexibility, portability, and a striking visual impact—plus, container grasses are easy to rearrange with the seasons.

Why Grow Ornamental Grasses in Containers?

  1. Enhances entrances, patios, and balconies
  2. Adds height and texture to container gardens
  3. Provides year-round structure and movement
  4. Perfect for small spaces and renters
  5. Minimal watering and maintenance required

Many ornamental grasses require very little fertilizer and thrive even in less-than-perfect soils, making them ideal for busy gardeners.

Simple Steps to Grow Ornamental Grasses in Containers

If you’re new to growing grasses, don’t worry—it’s easy and rewarding. Here’s how to get started:

1. Add the Right Soil

Choose a well-draining potting mix. Grasses prefer slightly moist soil but hate soggy conditions. For best results, fill your container about three-quarters full and gently moisten the soil before planting.

2. Select Your Grass Variety

Pick grasses suited for container growth and your local climate. Choose based on height, color, texture, and sunlight requirements.

Some excellent container grasses include Red Fountain Grass, Fiber Optic Grass, Ravennagrass, and Japanese Forest Grass.

3. Sow Seeds or Plant Starters

If growing from seed, sprinkle them evenly over the surface and lightly cover with soil. For faster results, consider using young starter plants from a nursery. Plant them at the same depth they were growing previously.

4. Position for Sunlight

Most ornamental grasses thrive in full sun, although some varieties, like Japanese Forest Grass, prefer partial shade.

Place your containers where they will receive at least 6 hours of sunlight daily unless the variety prefers less.

5. Water Sparingly

Water only when the top inch of soil feels dry. Grasses are highly drought tolerant once established and may need less water during rainy weeks. Always allow the soil to dry slightly between waterings to prevent root rot.

Best Ornamental Grasses for Containers

Here are some top-performing ornamental grasses that look stunning in pots and planters:

1. Red Fountain Grass (Pennisetum setaceum ‘Rubrum’)

Red Fountain Grass is a standout for containers, featuring narrow burgundy-red leaves that arch gracefully like a water fountain.

  • Height: 3 to 4 feet
  • Highlights: Rich color, feathery flower spikes
  • Best For: Sunny spots, creating dramatic focal points

Even in cooler climates where it’s treated as an annual, its fast growth and bold color make it a favorite for seasonal displays.

2. Fiber Optic Grass (Isolepis cernua)

This unique grass creates an enchanting, soft weeping effect with its fine, hair-like strands tipped with tiny “fiber optic” looking flowers.

  • Height: 6 to 12 inches
  • Highlights: Delicate, flowing form
  • Best For: Moist soils, near water features or indoors

Fiber Optic Grass loves moist conditions, making it ideal for planting near ponds or pools. It also thrives in containers with regular watering and partial sunlight.

3. New Zealand Flax (Phormium tenax)

Though technically not a true grass, New Zealand Flax offers striking, sword-like foliage that behaves much like an ornamental grass in landscaping.

  • Height: 3 to 9 feet, depending on variety
  • Highlights: Bold colors ranging from green to red, copper, and yellow
  • Best For: Modern landscapes, dramatic accents in large pots

Tough and architectural, it’s perfect for adding structure and exotic flair to your container garden.

4. Blue Oat Grass (Helictotrichon sempervirens)

Blue Oat Grass is prized for its cool blue-gray foliage and tidy, rounded form.

  • Height: 2 to 3 feet
  • Highlights: Silvery-blue color, low maintenance
  • Best For: Adding cool tones and texture to garden designs

This grass is a clumping variety, meaning it won’t spread uncontrollably, making it ideal for container gardening. It also produces lovely oat-like seed heads in summer.

5. Japanese Forest Grass (Hakonechloa macra)

Known for its flowing, elegant form, Japanese Forest Grass offers soft, arching mounds of green, gold, or variegated foliage.

  • Height: 1 to 2 feet
  • Highlights: Shade tolerance, graceful movement
  • Best For: Shaded patios, woodland gardens, under trees

Its cascading habit is stunning spilling out of a container, and its subtle colors blend beautifully with other shade-loving plants.

6. Pink Muhly Grass (Muhlenbergia capillaris)

Few plants are as eye-catching as Pink Muhly Grass, which bursts into a cotton-candy cloud of pink plumes in late summer and fall.

  • Height: 2 to 3 feet
  • Highlights: Airy, pink flower heads, drought tolerance
  • Best For: Autumn gardens, mass plantings in large containers

In addition to its show-stopping blooms, Pink Muhly Grass is hardy, heat-tolerant, and easy to maintain, making it a favorite for adding dramatic late-season color.

Growing ornamental grasses in containers is a beautiful, low-maintenance way to bring texture, movement, and structure to your garden, balcony, or front entryway.

With their easy care needs, drought tolerance, and year-round appeal, they are perfect for both novice and experienced gardeners.

Whether you prefer the bold burgundy of Red Fountain Grass, the shimmering elegance of Blue Oat Grass, or the breathtaking clouds of Pink Muhly Grass, there’s a perfect ornamental grass to enhance any outdoor space.

Plant a few varieties together for contrast and movement, and you’ll create stunning container gardens that look gorgeous through every season.
