Hi; some plants that are listed as 'parasitic' need the fungus that grows on
certain tree roots - there are many species of these fungi and they vary by
species of tree and geographic location.  Sometimes you can perpetuate the plant
by taking a good portion of the soil it is growing in with it to its new location,
but if the fungus absolutely needs oak roots and you can't provide them, the
fungus will not thrive and neither will the plant.
