I am interested in any experiences with any of these, and other
extreme vegetables not mentioned that are worth a go.

Not oca or Chinese artichokes - both good, but too much hassle
for the food value.

Nor arrowroot - easy to grow, but lacks the flavour of cotton wool.

Rampion. I have never got it to germinate.

Skirret. I didn't get it to germinate - is it worth the effort?

Where did you get the seeds from? I was tempted to get some this year
but didn't in the end as I got sent a T&M voucher and got everything I
needed from there.

Probably Chiltern. Pennard plants also say they have it.
