Stipa gigantea, commonly known as Giant Feather Grass, is one of the most spectacular ornamental grasses available for the garden. Forming a low, evergreen clump of narrow, arching green foliage, it sends up tall, elegant stems in early summer topped with open, oat-like panicles that shimmer and sway in the lightest breeze. These golden flower heads catch the sunlight beautifully, creating a dazzling, translucent effect that few other plants can match.

A firm favourite in contemporary and naturalistic planting alike, Stipa gigantea brings dramatic height, movement, and year-round structure to borders, gravel gardens, and prairie-style schemes — all with remarkably little maintenance.

Seasonal Beauty & Growth

Spring:
The semi-evergreen clump of fine, arching green leaves looks fresh and tidy as new growth gets underway. Tall flowering stems begin to emerge from the base.

Summer:
The plant reaches its peak as towering stems carry loosely branched panicles of golden, oat-like flower heads. These shimmer and catch the light, creating a breathtaking display of movement and luminosity above the foliage.

Autumn:
Flower heads deepen to rich amber and straw tones, remaining decorative well into the season and providing warm golden colour as other plants begin to fade.

Winter:
Dried stems and seed heads persist, adding skeletal structure and texture to the winter garden. The evergreen foliage clump remains intact, keeping the border looking furnished through the colder months.

The combination of low-growing foliage and soaring flower stems gives Stipa gigantea a unique transparency that allows planting behind it to remain visible, making it perfect as a see-through accent in the middle or front of a border.

Perfect for Various Landscapes

Mixed Borders: Adds impressive height and graceful movement without overwhelming neighbouring plants.
Gravel & Dry Gardens: Thrives in free-draining conditions, making it ideal alongside other drought-tolerant perennials and shrubs.
Prairie & Naturalistic Planting: Pairs beautifully with flowering perennials such as Echinacea, Salvia, and Achillea in relaxed, meadow-inspired schemes.
Architectural Planting: A bold vertical accent that provides structure and elegance in formal or contemporary designs.
Wildlife Gardens: Seed heads attract birds and provide habitat for beneficial insects through autumn and winter.

Growing Conditions

Position:
Full sun is essential for the best flowering and strongest growth. Stipa gigantea thrives in open, sunny locations where air can circulate freely around the stems.

Soil:
Prefers well-drained to dry soil. It is highly tolerant of poor, sandy, or stony soils and performs particularly well in free-draining conditions. Avoid heavy, wet, or waterlogged ground, especially over winter, which can cause the clump to rot.

Hardiness:
Hardy in most parts of the UK, tolerating temperatures down to approximately -10°C to -15°C. Good drainage is the key to successful overwintering.

Care & Maintenance

Watering:
Once established, Stipa gigantea is drought tolerant and requires little supplementary watering. Young plants benefit from occasional watering during dry spells in their first season while they settle in.

Feeding:
No regular feeding is necessary. Overly fertile soils can lead to lax, floppy growth — this grass is at its best in lean, well-drained conditions.

Pruning & Tidying:
In early spring, before new growth begins, remove any dead or tatty foliage from the clump. Old flowering stems can be cut back at the same time. Avoid cutting into the crown too hard — simply tidy rather than cut back severely, as Stipa gigantea does not always recover well from drastic pruning.

Division:
Clumps can be divided in spring if they become very large, though Stipa gigantea generally performs best when left undisturbed for several years.
