 icon of manicon of flower
Cortaderia selloana is an evergreen Perennial growing to 3 m (9ft) by 1.2 m (4ft in) at a fast rate.
It is hardy to zone (UK) 5 and is not frost tender. It is in leaf 12-Jan It is in flower from Aug to October, and the seeds ripen from Oct to November. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Wind.The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.

Other Uses
Fibre;  Paper.

A fibre obtained from the leaves is used for making paper[46, 61, 74, 189]. The leaves are harvested in the autumn, they are cut into usable pieces and soaked for 24 hours in clear water. They are then cooked for 2 hours with lye and then beaten in a blender. The fibre makes a yellow paper[189]. The feathery flower head plumes, when dried, are widely used in flower arrangements and other ornamental displays.
Cultivation details
Agroforestry Services: Windbreak;  Industrial Crop: Biomass;  Management: Hay;  Minor Global Crop.

Landscape Uses:Container, Massing, Specimen. Succeeds in most soils, preferring a damp well-drained sandy or loamy soil[1]. Inclined to be intolerant of cold clay soils[162]. Succeeds in dry soils. Prefers a sunny sheltered position[1, 162, 200]. Very tolerant of maritime exposure[K]. This species is hardy to about -20°c[187] if the winter is not excessively wet, though it is intolerant of prolonged periods of cold weather. Pampas grass is occasionally cultivated in some areas for its fibre which is used in making paper. Plants grow well as a focal point in a lawn and they also succeed in quite coarse grass[1, 233]. A number of named forms have been selected for their ornamental value[187, 200]. The leaves have saw-toothed edges, it is best to wear gloves when working with the plant[200]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233]. Dioecious. Male and female plants must be grown if seed is required[200]. The inflorescence on the male plant is rather erect whilst it has wide spreading branches on the female[187]. Special Features:Attracts birds, Attractive foliage, Not North American native, Suitable for cut flowers, Suitable for dried flowers, Attractive flowers or blooms.
Seed - surface sow March/April in a greenhouse. The seed usually germinates in 2 - 3 weeks at 15°c. Keep the soil moist. The seed has a short viability[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in late spring[1]. It can be very difficult to obtain divisions from this plant because they tend to be very large and to be very close to the main clump. We have found it best to use a sharp spade to cut into the main clump and break off the divisions. These are then potted up in light shade in a cold frame and are planted out once they have rooted well and are in active growth.

Other useful Cortaderias. There are four species of Cortaderia native here in New Zealand, which I think might be of interest as they have similar landscaping uses:barriers and low windbreaks, look much the same and are similar in size. I think some of the following uses might also work with Cortaderia selloana The leaves were used by Maori for making mats ,kites, baskets and containers for steeping and boiling food in water The flower heads wre used for sieves or strainers ( this could be of use again when we run out of metal for kitchen utensils) The heads were also used to stop the flow of blood (from wounds I guess) The base of the leaf was chewed for diarrhoea and kidney problems.

Crow says he finds the base of the stem the most palatable part but says some have tried the apparantly hard roots as food.

I chewed on several leaf bases yesterday and found them to be good thirst quenchers, you have to chew and suck out the flesh from around inedible fibres, taste not bitter or sweet, perhaps mushy potato chip-ish. A cigarette substitute perhaps( the sucking).

Crow lists it in the back of his excellent book under somewhat uncertain edibles so care would be advised.

The main native species sold here are Cortaderi toe toe & C.fulvida, no idea if available overseas.
