Sow and Plant

Miscanthus has invasive potential in some climates, especially when older seed-sown strains are grown. Many modern cultivars are considered seed sterile, so they are propagated vegetatively and must be started from purchased plants. Set out container-grown plants from spring to early summer in sunny, well-drained soil. Young plants need water their first year, but after that miscanthus becomes very drought tolerant. Miscanthus is very fast to establish and forms a vigorous clump by its second year. You can increase your supply of plants by digging divisions from the outside of the clump in late spring and transplanting them to a new location.

The vase-shaped form and soft texture of miscanthus are beautiful through summer, and then the plants develop showy tops that persist into winter. Wind and light dramatise the best features of miscanthus. In winter, after the tops have broken and withered, use a hedge trimmer to cut the plants back to about 10cm (4 inches) from the ground.


The leaves and seed heads can be used in cut arrangements.


This easy to please grass rarely has few problems with pests and disease and is resistant to nibbling by deer and other animals.
