This can be seen in various locations around the Woodland Garden. It is a semi-parasitic plant which absorbs nutrients from host plants. It has totally lost its chlorophyll and has no photosynthesizing capacity hence a lack of green leaf or stalk.
Willows are one of the main hosts here in the Garden.
The plant taps into the host plant via a specialist root attachment called an haustorium which allows the syphoning off of food reserves and nutrients necessary for growth.
