Gastrodia cunninghamii Cultivation | Propagation | General Uses Cultivation Notes: We have very little information on this species and do not know if it will be hardy in Britain. A saprophytic herb, it is without green parts and is entirely dependant upon a fungus for its nutriment[238]. This makes it very difficult to cultivate outside its native range. As well as its fungal host, it also requires a damp humus-rich soil in a sheltered woodland position[238]. The freshly opened flowers have a refreshingly aromatic scent, though this becomes foetid and unpleasant as the flowers fade[245]. Orchids are, in general, shallow-rooting plants of well-drained low-fertility soils. Their symbiotic relationship with a fungus in the soil allows them to obtain sufficient nutrients and be able to compete successfully with other plants. They are very sensitive to the addition of fertilizers or fungicides since these can harm the symbiotic fungus and thus kill the orchid[230].
