Weeping Grass

Microlaena stipoides

grass

Weeping grass is a fine-textured, cool-season perennial grass native to Australia with delicate, drooping foliage that creates an elegant cascading effect in gardens. It produces small, inconspicuous flowers and is valued primarily for its ornamental foliage rather than its seed heads. This grass is drought-tolerant once established and provides year-round visual interest with minimal maintenance.

Growth Stages

1

Seedling/Establishment

4-6 weeks

Fine, delicate leaf blades emerge; plant is low and spreading. Growth is slow initially.

Keep soil consistently moist but not waterlogged. Protect from direct intense heat. Avoid foot traffic.

2

Vegetative Development

2-3 months

Foliage spreads outward in a mounding habit; characteristic weeping, drooping form becomes apparent. Plant reaches 6-12 inches tall.

Water moderately as needed. Begin light fertilization with balanced slow-release fertilizer in spring. Mulch lightly around base.

3

Maturation

Ongoing from year 2 onward

Plant fills out to full mature size (12-18 inches tall and wide), with dense, graceful cascading foliage creating elegant mounding form.

Reduce watering frequency; established plants are drought-tolerant. Light spring fertilizer optional. Avoid excessive nitrogen which reduces ornamental quality.

4

Flowering

4-8 weeks

Produces small, delicate flower spikes in spring to early summer; flowers are insignificant and are not the ornamental feature of this grass.

No special care needed for flowers. Some gardeners remove spent flower heads for neater appearance, though this is optional.

5

Dormancy/Winter

3-4 months (zone dependent)

Foliage may take on bronze or reddish tones in cooler zones; growth slows significantly. Plant remains evergreen to semi-evergreen depending on zone.

Minimize water in winter months. Avoid pruning in late summer as this can stimulate tender new growth vulnerable to frost. Prune lightly in early spring.

Companion Planting

Plan your garden →

Plant with:

Avoid planting near:

Highly competitive perennials (e.g., some bamboos) Plants requiring consistently wet soil (contraindicated by drainage needs) Tall plants that shade and suppress growth

Common Pests

  • Usually minor issue; use insecticidal soap if severe. Encourage natural predators like birds.

  • Improve air circulation, avoid overhead watering, remove affected foliage. Fungicide spray if widespread.

  • and

    Copper tape barriers, hand removal, or slug pellets. Encourage ground beetles and toads.

Uses

🌿

Accent and Border Planting

Ornamental

Weeping grass serves as an elegant specimen plant or accent in shaded to part-sun gardens, creating graceful mounding form that softens hardscapes and complements shade plantings. Its fine texture contrasts beautifully with broad-leaved perennials and shrubs. [source]

🦋

Native Habitat for Australian Wildlife

Wildlife

As a native Australian grass, weeping grass provides habitat and food for native Australian insects and small animals in gardens. In non-native regions, it supports general beneficial insects including pollinators. [source]

🏠

Xeriscape and Low-Maintenance Gardening

Household

Once established, weeping grass requires minimal water, fertilizer, and maintenance, making it ideal for drought-tolerant and sustainable garden designs with reduced environmental impact. Its low fertility needs reduce fertilizer application requirements. [source]

🎨

Cut Foliage for Arrangements

Craft

The delicate, graceful stems and fine foliage can be used fresh in floral arrangements and garden bouquets, providing elegant, airy texture to cut flower designs. [source]

Harvest Tips

Weeping grass is an ornamental rather than a harvested plant. Prune lightly in early spring to remove dead or damaged foliage and shape if desired. Do not cut back severely or remove more than one-third of foliage at once. Deadheading spent flower heads is optional for appearance. Avoid pruning in late summer.

Fun Facts

  • 🌱 Weeping grass is native to southeastern Australia and has been called 'Australian weeping grass' to distinguish it from unrelated grasses in other regions.
  • 🌱 The scientific name Microlaena means 'small cloak' in Greek, referring to the delicate, fine-textured foliage that appears to drape gracefully like a soft garment.
  • 🌱 Despite its delicate appearance, established weeping grass is remarkably drought-tolerant and requires significantly less water than many shade-loving perennials, making it an excellent choice for water-wise gardens.
