How it is grown
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. It probably does not have any special cultivation requirements and will probably succeed in most soils in a sunny position. There is a lot of confusion over the correct name of this species. According to the Russian flora C. sibiricum. (L.)R.Br. is a synonym of Antitoxicum sibiricum. (L.)Pobed. a perennial that grows to 45cm on sandhills, in pine woods, steppe and rocky slopes from W. Siberia to China. The same flora mentions C. sibiricum. Willd, a perennial that is very closely related to C. acutum (q.v.) and grows on tugail soils by rivers and brooks, irrigation canals, alluvial and sand dunes. We cannot be sure which of these species is meant in the reports of edibility.
Propagating it: Seed - sow spring in the greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring.
