Ornamental grasses are all the rage, and with so many varieties suited to a wide range of climates and garden situations, miscanthus are a top pick. Sometimes known as silver grass, these plants are dependable, varied and valuable, and are a key ingredient if you're interested in planting a prairie garden.
With varieties small enough for a pot on the deck, to large enough for a back-of-the border specimen, miscanthus grasses bring together two main features – foliage and flowers.
In spring, slender shoots emerge from the tightly clumping plants and develop into long narrow leaves up to 4ft long and up to 12in across. In some varieties the leaves are toothed along the edge and gloves are recommended.
There is a central white stripe running down through each leaf in some varieties, while in others there are white margins to each leaf. In a few, the leaves are cross-banded horizontally in yellow.
In the fall, many varieties develop bright and fiery, red and orange and golden yellow tones.
The flower heads emerge from late summer to late fall, in the form of feathery plumes in white, beige, pink or mahogany. As the weeks pass the plumes tend to become fluffy and mature into biscuit tones, sometimes remaining in place through the winter.
Flowering is most prolific in areas with hot summers and where fall comes late, in areas with cooler summers and an early fall some varieties may not flower at all.
'Graceful and robust, miscanthus are favored for their luxuriant foliage and silky terminal panicles,' say the experts at California’s Digging Dog Nursery. 'Striking as singular specimens, miscanthus are also excellent when massed in the perennial bed or a mixed border. Attractive throughout most of the year, with yellow, purple, scarlet and burgundy fall colors, they fade to a lovely warm ivory in winter.'

FAQs
Is miscanthus deer resistant?
Generally speaking, yes. At New Jersey’s Rutgers University, the Agricultural Experiment Station has been studying which plants are resistant to deer browsing and which are not. The result is that they have graded a large number of popular, and not so popular plants, in one of four categories.
Miscanthus fall into the 'rarely damaged' category, the top rate for deer resistance, which means exactly that. Miscanthus are rarely damaged, partly because many varieties have small, very sharp teeth along the edges of the leaves.
Is miscanthus invasive?
Miscanthus is increasingly seen as a potential invasive, especially in the east. It has been noted as invasive in twenty five states, DC, and also in Ontario.
It spreads by seed but it’s often said that some varieties are sterile and never produce seeds. However, the Chicago Botanic Garden researched thirty four varieties and found that only four varieties failed to produce seed: ‘Cabaret’, Little Nicky (‘Hinjo’), and the rarely seen ‘Silberpfeil’ plus elephant grass (Miscanthus x giganteus).
Research also suggested that in more favorable growing areas ‘Cabaret’, Little Nicky (‘Hinjo’) and ‘Silberpfeil’ would probably also produce seeds and only elephant grass (Miscanthus x giganteus) would never produce seeds. But of course elephant grass, once established, can spread strongly at the root.
In areas with cool summers, many varieties of miscanthus will not flower and so will produce no seeds and so will not spread. If in doubt, only grow foliage varieties that do not flower in your area.
Can I grow miscanthus in a container?
Yes. Almost all miscanthus can be grown in pots. In fact they have a useful feature that makes them especially valuable for container growing.
Varieties that are naturally shorter will thrive in pots and may well mature at their usual height, especially if fed and watered regularly. However, most taller varieties will also grow well in containers, but will simply mature as shorter plants.
It pays to plant taller varieties in concrete, terracotta or stone pots because their weight will help prevent the pot blowing over in a gale. Choose a soil-based planting mix, and try to keep the pots consistently moist as if they dry out the plants will tend to lose their lower leaves which spoils the display.
Planted with care and respect for your local environment, miscanthus grasses are hard working without requiring too much attention. If you are planning to add some to your yard, it might be useful to know when to cut back ornamental grasses, so you can properly maintain the size of your plants by cutting back miscanthus each year.
