PlantFiles: Ayahuasca
Banisteriopsis caapi

I've also had good success indoors, but have heard first hand accounts of well established B. caapi vines surviving frosts overnight; nonetheless I agree, it's probably not wise to let it get too cold.

Also, it's worth noting the value of this houseplant OUTSIDE the realm of it's role in the shamanic tradition. It's a fast growing, enjoyable foliage plant, and need not be abused for it's alkaloid content. When taken in combination with any DMT containing plant, like P. viridis, but without a shaman, it's nothing more than a necessary counterpart to a recreational drug.

Also known as YAGE, The principal ingredient in the drink Ayahuasca, used by South American Shaman. The other plant used is Psychotria virdis, The vine can grow very large and reach to the top of the rain forest trees. The Picture I uploaded is of a plant growing in my greenhouse, I don't supose it would be cold tolerant enough to grow outside here. It has taken 4 years for the plant to reach the size pictured.
