100yrs letshope not! 
Indonesian members have said it has a very deep taproot...so I figure mine are at the bottom of the pot by now for sure. Time to put in ground. But how and where! Could it be invasive?
Recently got some other liana/vine type fruit from Luc. Immediately they were popping, then I waited a bit too long and noticed no more growth, so I pulled it out of the shallow pot to find the roots stopped going down and just got thicker and thicker...stunted for sure. I'm to scared to pull up willughbea sp and ch ck but I suspects it's the same trip...
How deep are your pots you have these rare liana in?
Oh well, maybe that's the reason for slow growth. No space for tap root, because they were kept at US 1 gallon equivalent. Upgraded to much bigger bags and let's see what happens. I highly doubt they are invasive because of the rarity, slow growth, and the fact that flesh sticks to the seed. It has much bigger chance to rot in nature than sprout.
I personally would not put these anywhere in the garden. Only in a wild or private semi wild forest.
I don't know if you have such ability in US, but I buy a polythene roll of nursery bags (not cut, continuous roll). Than I buy cheap sealer. I think they were around $15. It gives you ability to make custom depth growing bags. As deep as you need. Also you make custom drainage holes on such set up.
