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[

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.

]. 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.

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.
