Physical Characteristics

Perennial growing to 1.2m. It is hardy to zone 5. It is in flower from July to September, and the seeds ripen from September to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Wind. We rate it 3/5 for edibility and 0/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure.

Habitats and Possible Locations

Cultivated Beds.

Edible Uses

Seed Stem.

Seed - used as a cereal substitute in some parts of Russia, especially in times of drought[183]. The seed is rather small and difficult to extract[K].
Young underground shoots - raw. Sweet and tender[183].

Medicinal Uses

Disclaimer

None known

Other Uses

Oil Soil stabilization.

Plants have an extensive spreading root system and are used to stabilize inland sand dunes, though they do not tolerate salty conditions[61].

Cultivation details

Succeeds in most soils, preferring a sandy soil and a sunny position[1, 200]. Established plants are drought resistant[183]. Plants can be very invasive, spreading freely by means of the rhizomes.
Currently (1990) being evaluated as a perennial grain crop in N. America[183].
There are some named varieties, selected for their ornamental value[200].

Propagation

Seed - sow mid spring in situ and only just cover the seed[162]. Germination should take place within 2 weeks.
If the supply of seed is limited, it can also be sown in mid spring in a cold frame. Only just cover the seed. When large enough to handle, prick the seedlings out into individual pots and plant them out in summer[K]
Division in spring or summer[162]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
