Greerish's Parasite garden

Well at the moment its not quite a garden, I mean how can one plant be a garden. This is more an idea I’ve had for a garden thats been hanging around in the aether as it were. At my last college I spent alot of time looking at how plants adapt to an environment (actually I’ve been doing that for a while its how I got into Orchids and Aeoniums) I found this book in the college library I think it was called The Nature of Plants: Habitats, Challenges, and Adaptations. one of the first chapters was on how plants use other plants to survive And one of the first pictures was of a mistletoe species from New Zealand Peraxilla tetrapetala and the more I read the more interested I got so now I want to see if I can grow these plants in the garden or as house plants, I’m thinking that if you have a plant that has been parasitised in a garden you could treat the host plant in a way that would keep it healthy (I hope so any way)
