Are you experienced with growing plants this difficult? I'm big into plants and spend a lot of time reading about plants like these and it always saddens me to read about cool plants and then see that they're endangered because of wild harvesting to sell on the market. I always wonder who the hell is buying this. B. trifoliolata has not yet been evaluated for whether or not its endangered and it's unlikely it will any time soon since parasitic plants are notoriously hard to diagnose. Please don't go out searching for this unless you're absolutely sure you have the equipment and knowledge necessary to actually propagate this plant. A quick search on the Tropical Fruit Forum[1] shows that no one else has really had much success in cultivating this

I just want to study it more as it is a pretty fascinating plant.
Nobody expects it to survive and propagate outdoors.
