How it is grown

Requires a well-drained soil, preferably on the dry side. Grows well in a woodland garden. This species is not very hardy outdoors in Britain, tolerating temperatures down to between -5 and -10°c. A semi-parasitic plant, thus making it very difficult to establish in cultivation. We are not sure which species it parasitizes.
