Physical Characteristics
Annual growing to 1.5m by 0.3m at a fast rate.
It is hardy to zone 0 and is frost tender. It is in flower from July to September, and the seeds ripen from August to October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Bees, flies.
It is noted for attracting wildlife.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay and nutritionally poor soils.
The plant prefers acid, neutral and basic (alkaline) soils and can grow in very acid soil.
It cannot grow in the shade.
It requires dry or moist soil and can tolerate drought.
Leaves - raw or cooked like spinach[4, 183, K]. Not that wonderful raw, they improve somewhat with cooking[K]. The leaves are rich in rutin[171] (see below for more details) and so are a very healthy addition to the diet[K].
Seed - raw or cooked. A nutty flavour, though it has a somewhat gritty texture[K]. The seed can be soaked overnight in warm water then sprouted for a few days and added to salads[183]. It can also be ground into a powder and used as a cereal[2, 4, 9] when it can be made into pancakes, noodles, breads etc or be used as a thickening agent in soups etc[46, 183]. Rich in vitamin B6[160]. An excellent beer can be brewed from the grain[244].
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants.
Always seek advice from a professional before using a plant medicinally.
Buckwheat is a bitter but pleasant tasting herb that is frequently used medicinally because the leaves are a good source of rutin[238]. Rutin is useful in the treatment of a wide range of circulatory problems, it dilates the blood vessels, reduces capillary permeability and lowers blood pressure[238, 254].
The leaves and shoots of flowering plants are acrid, astringent and vasodilator[4, 141, 165]. It is used internally in the treatment of high blood pressure, gout, varicose veins, chilblains, radiation damage etc[4, 141, 165]. It is best used in conjunction with vitamin C since this aids absorption[254]. Often combined with lime flowers (Tilia species), it is a specific treatment for haemorrhage into the retina[254]. The leaves and flowering stems are harvested as the plant begins to flower and are dried for later use[238]. They should be stored in the dark because the active ingredients rapidly degrade in the light[238]. Some caution should be exercised in the use of this herb because it has been known to cause light-sensitive dermatitis[238].
A poultice made from the seeds has been used for restoring the flow of milk in nursing mothers[4].
An infusion of the herb has been used in the treatment of erysipelas (an acute infectious skin disease)[4, 244].
A homeopathic remedy has been made from the leaves[9]. It is used in the treatment of eczema and liver disorders[9].
A very good green manure plant, it can be used to reclaim badly degraded soils and subsoils[1, 18, 20, 201].
A blue dye is obtained from the stems[57, 106].
A brown dye is obtained from the flowers[4].
Scented Plants
Flowers: Fresh
The flowers have a pleasant sweet honey smell.
Cultivation details
A very easily grown plant, it prefers dry sandy soils but succeeds in most conditions including poor[57, 141, 171], heavy[18] or acid soils[141] and even sub-soils[160]. Prefers a cool moist climate, but it also succeeds in dry and arid regions[171].
Buckwheat is frequently cultivated for its edible seed and leaves, it can produce a seed crop in 100 days from sowing[141] and a crop of leaves in 8 weeks. There are some named varieties[183]. The seed ripens irregularly over a period of several weeks so it is difficult to harvest[141].
Plants have poor frost resistance but they are disease and insect resistant[166]. They inhibit the growth of winter wheat[18, 20, 201].
The flowers have a pleasant sweet honey scent[245] and are extremely attractive to bees and hoverflies[4, 171].
Propagation
Seed - sow from the middle of spring to early summer in situ. The seed usually germinates in 5 days[115]. The earlier sowings are for a seed or leaf crop whilst the later sowings are used mainly for leaf crops or green manure.
Cultivars
'Giant American'
Produces the largest seed of any buckwheat cultivar, also the heaviest seed per 100 seed weight[183]. Yields average to above average crops[183].
A medium-tall plant to 1.2 metres tall, it blooms in 30 days from sowing[183].
'Mancan'
An improved form that yields a nutritious grain within 80 days from sowing, the plant flowering after 30 days[183]. It yields average to above average crops[183].
A medium-tall plant[183].
'New Type'
A heavy cropper that is less likely to blight than other sorts[183]. The kernels are larger and the straw is stouter and heavier[183].
'Spanky'
An improved form that makes excellent flapjacks[183]. Planted late to mature in the autumn, it ripens a crop in 2 - 3 months[183].
