Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

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].
