Cultivation details
A semi-parasitic plant, growing on grass roots. Rather difficult to establish in cultivation, it is best grown in conditions that approximate to its native habitat[200]. It requires a moist peaty soil and the presence of host grasses[1]. The plant is said to parasitize at least 80 different species in 35 different genera[274]. Requires a partially shaded to sunny site in a well-drained gritty but moist soil[200].
Propagation
Seed - sow in pots of turf collected from the proximity of wild colonies or sow directly onto the sites where the plants are to remain[200]. Division of established plants might be possible in the spring. Establish the divisions near the parent plants[200]
