Japanese hardy ginger / Zingiber mioga

[Sadik]

Anyone grown this? Wondering what size container it would need - lots of information about growing it online, and lots saying it can be grown in a container, but can't find a single comment on size!

I have one which I put in the ground last year and it grew up nicely and then apparently died (from lack of water I thought). I dug it up and chucked it in a pot on the off chance of revival and forgot about it over the winter and it currently has two new shoots. It is currently in an approx 6" wide and deep pot, and I might keep it in a pot this year because the slugs liked it last year. If I do then it will be in a 12" wide and 18" deep one with a self watering function - I don't think they cope well with drought.
