I've read about yacón for several years but have never grown it. I guess the first question I have is does it cause extreme GI distress a la Jerusalem artichokes?

I've seen some articles suggest that they sweeten over time in storage yet others talk about the tubers losing something over time in storage. Which is it?

I read somewhere a long time ago that the leaves were also good and used for stuff like wraps, rolls, etc. Can anyone comment on palatability?

re: space, time, life, the universe, and everything... - what are the realistic needs of this plant?

I tried it my climate is not like yours I'm only heatzone 1/2 but it grew here, it takes very little space, it looks like a Jerusalem artichoke but doesn't get anywhere near as tall and grows a clump of tubers like a dahlia.

The tubers were very bland fresh with a slightly sweet piney taste, they didn't seem to change with storage at all. I did not manage to keep any of them overwinter, they dried out while all of the dahlias they were sharing a tub with were fine so I decided they are more effort than they are worth for me.
As for gas production they were exactly the same as Jerusalem artichokes for us.
