Apparrantly a guy on this forum called Carlos Rohrbacher from brazil has an eden black ceph, don't know if it's the real deal though. Might have better luck and be quicker getting something from him.
if correct would be interested to know where he got it from, not from me!
importing plants from Brazil to USA will still need phytosanitary and import docs. seed will also still need APHIS permits.
so not sure it would be quicker.
I am happy to send seed when I next have it, provided the right permits are in place.
