OK
As a reminder these, one pink and 3 white, came from Greece and arrived in a terrible state. All their 'fingers' were broken off and rot had set in. I got a refund. I cut off all black which left very little and basically just the 'hand' of the tubers. I let them dry out for a while and potted them. I was amazed to see noses appear in late winter. The pink and two whites flowered. I repotted them this afternoon. The pink one made an OK new tuber but the white ones have made very large tubers with roots already reaching the bottom of the pot they are in
