The devil's tongue plants I have, have the roots, so they should be able to be planted, and nurtured, although I don't know how many you'd like.

The same goes for the passionflora plants, they don't have the roots but they are cuttings, they should work.

The seeds are from the cocoa pods are still encased and just in a jar for the prep time that takes. I don't know if there is enough room for trees in there.
