Hi again - I'm waiting for some ginger seeds to germinate - Cautleya lutea which was described as hardy to -10C so will see what happens !! I've never grown ginger of any type before and am thinking of ordering a Roscoea next Spring which I believe is also hardy.
Like you welshonion I don't want anything that is too time consuming or requires lots of space as both time and space, as well as funds, are limited !!
Happy gardening to you both
