Cortaderia 'White Feather' (White Pampas Grass)

A Classic Grass with Bright White Plumes

Cortaderia 'White Feather' is a pampas grass that brings real presence to the garden. It forms a large, fountain-like clump of arching evergreen leaves. From late summer, tall, sturdy stems rise well above the foliage, each topped with a big, fluffy plume in creamy to silvery white. These bright plumes stand out against the sky and glow in low autumn sunshine. They often last well into winter, giving you a long season of interest from a single plant.

White pampas is a timeless look, and it has become fashionable again for good reason. Its clean, bright plumes suit modern, minimalist gardens just as well as relaxed, naturalistic planting. It combines easily with almost any colour scheme.

Key Features

• Large, creamy-white feathery plumes from late summer through autumn, often lasting into winter

• Evergreen, arching foliage that provides structure all year round

• Tall, eye-catching stems, perfect as a focal point or living screen

• Fully hardy in most UK gardens once established

• Easy to care for, needing little more than a yearly tidy

• Drought tolerant once settled, and a good choice for coastal gardens

• Superb for cutting and drying, making elegant indoor displays

Size and Growth

'White Feather' is a big plant, so plan for plenty of space. When mature, the flower stems typically reach around 2 to 2.5 metres (roughly 7 to 8 feet), with a spread of about 1.5 metres. The mound of foliage usually sits at around 1 to 1.5 metres high. It grows steadily and will usually reach its full size within a few years.

Where to Plant

This is a sun-loving grass that performs best in an open position. For the best results:

• Position: Full sun is ideal. It will put up with a little light shade, but you'll get the most plumes in sun.

• Soil: Most well-drained soils suit it, including sandy and chalky ground. Avoid soil that stays wet and soggy through winter.

• Exposure: It handles wind and salty air well, making it a dependable choice for seaside gardens.

The leaves have sharp edges, and the plant grows large. Give it a spot away from paths, seating areas and places where children play.

Garden Uses

'White Feather' is adaptable and can play several roles in the garden:

• As a standalone specimen in a lawn, gravel bed or large island border

• At the back of a border, giving height and structure behind lower plants

• In naturalistic and prairie-style schemes, mixed with other ornamental grasses and late perennials such as echinaceas, verbena bonariensis and asters

• In coastal and gravel gardens, where its resilience comes into its own

• As an informal screen or windbreak, softening fences and boundaries

• Against dark backgrounds, such as evergreen hedges or dark fencing, where the white plumes really stand out

• In large containers, provided it's watered regularly and given a generous pot

Planting Guide

Spring is the ideal time to plant, as it gives the roots a full season to establish before winter. Container-grown plants can be planted at most times of year, as long as the ground isn't frozen or waterlogged.

1. Dig a hole roughly twice as wide as the pot and just as deep.

2. Loosen the soil at the base and sides of the hole. On heavy clay, work in some horticultural grit to help drainage.

3. Set the plant in the hole so it sits at the same depth as it was growing in its pot.

4. Backfill with soil, firm gently around the roots and water thoroughly.

5. Keep it well watered during dry spells for its first growing season.

Care and Maintenance

Once it has settled in, 'White Feather' is a very undemanding plant.

Watering

Water regularly during its first year, particularly in warm, dry weather. After that, it copes well with drought and usually needs no extra watering. The exceptions are long dry spells and plants grown in pots.

Feeding

Pampas grass doesn't need much feeding. A light application of general-purpose fertiliser in spring is enough, and on decent soil it may not need any at all.

Pruning and Tidying

The one essential job is an annual tidy-up in late winter or early spring, before fresh growth starts:

• Cut the old flower stems down to the base.

• Clear out dead, brown leaves. Wearing thick gloves and long sleeves, you can comb through the clump with a gloved hand or a rake to pull out the old growth.

• Every few years, you can cut the whole clump back hard to around 30 to 60 centimetres to rejuvenate it. Take care not to damage any new shoots coming through.

Don't be tempted by the old method of burning the clump. It can seriously damage or kill the plant, and it's a real fire risk in the garden.

Using the Plumes Indoors

The white plumes are ideal for drying and are very popular in home décor. Cut them when they've just opened and are at their fluffiest, then hang them upside down somewhere dry and airy for two or three weeks. A light mist of unscented hairspray helps to reduce shedding. Dried white pampas keeps its good looks for months. It's lovely in tall vases, wedding and event arrangements, wreaths and seasonal displays.
