The packet is very ambiguous. Would you risk this outside in Yorkshire?
Just try some in and some out.
That's what I was thinking,but if anyone knows how hardy they are it would be useful to know!
The summer wouldnot be a problem,i think till the first frost you are save.There are other problems to deal with.
I think I would go for 'where I've got room for'.
If I've got plenty of room for them indoors, then that's where I would grow them. If not, then outdoors it has to be. ;D
