Physical Characteristics

 icon of manicon of flower
Taraxacum kok-saghyz is a PERENNIAL growing to 0.3 m (1ft) by 0.3 m (1ft in). It is in flower from May to June, and the seeds ripen from June to July. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Edible Uses

Edible Parts: Flowers  Leaves  Root
Edible Uses: Coffee  Tea

Leaves - raw or cooked[K]. The following uses are also probably applicable to this species, though we have no records for them[K] Root - cooked[183]. Flowers - raw or cooked[183]. The unopened flower buds can be used in fritters[183]. The whole plant is dried and used as a tea[177, 183]. A pleasant tea is made from the flowers. The leaves and the roots can also be used to make tea. The root is dried and roasted to make a coffee substitute.

Other Uses

Alcohol  Latex

The root is a source of a high quality latex, used in making rubber[1, 46, 61, 110]. Yields between 150 and 500 kilos per hectare are possible[110, 171]. The roots are harvested in the autumn, before any hard frosts which can destroy some of the latex. They are then macerated to extract the latex. The root is rich in the starch inulin. After the latex has been extracted, this inulin can be converted to alcohol and used as a fuel.

Cultivation details

Succeeds in ordinary garden soil[1] but prefers a well-drained moisture retentive humus-rich soil in full sun or light shade[110]. Prefers a pH between 5.5 and 8.5[110]. Dislikes very heavy or compacted soils[110]. Top growth of seedlings is very slow at first until the root has developed[110]. It is advantageous to mark out the rows with a catch crop such as radishes or lettuce[110]. This plant used to be grown commercially in Russia as a rubber producing plant. It was trialed in various countries during the second world war and was found to yield a commercial harvest in Britain, Scandinavia and Northern N. America. In a trial in N. America plants grew better in the northern U.S.A. and S. Canada than they did in the south of the USA[141]. With the advent of cheap artificial rubber interest in this plant dwindled. Many species in this genus produce their seed apomictically. This is an asexual method of seed production where each seed is genetically identical to the parent plant. Occasionally seed is produced sexually, the resulting seedlings are somewhat different to the parent plants and if these plants are sufficiently distinct from the parents and then produce apomictic seedlings these seedlings are, in theory at least, a new species.

Plant Propagation

Seed - sow spring in a cold frame and either surface-sow or only just cover the seed. Make sure the compost does not dry out. Germination should take place within 2 weeks, though 2 weeks cold stratification may improve germination. Prick out the seedlings into individual pots when they are large enough to handle, choosing relatively deep pots to accommodate the tap root. Plant them out in early summer. Division in early spring as the plant comes into growth.

how exactly is the latex extracted from the plant?

Song jun ho   Thu Jan 11 2007

how exactly is the latex extracted from the plant. Where can get the seed of Taraxacum kok-saghyz.

Ken Fern, Plants for a Future   Sun Jan 21 2007

The simplest method of extracting the latex is by totally macerating the plant in water, the latex then floats to the surface. As regards obtaining seed, your best bet would be to contact various botanical gardens, especially those in Russia and China. The plant is often grown in Botanical Gardens and many of these will supply seed to interested parties.

can you get latex from common dandelions (taraxacum officinale)?

Taraxacum Officinale

EU-PEARLS is a European Research project (FP7) aiming to develop two alternative plant sources of natural rubber and latex: guayule and Russian dandelion (Taraxacum kok-saghyz).   Dec 2 2010 12:00AM

I represent a European research project (link below) trying to develop TKS for rubber and latex production. One discovery was that the dandelion species labeled as TKS in botanical gardens is actually another species: Taraxacum brevicorniculatum. We collected new germplasm in Kazakhstan, which revealed that both species occur in the same environment, and that T. brevicorniculatum is much more vigorous: it overgrows TKS in a few years. I can also send you pictures of true TKS, and more information ([email protected]).
