I potted one wee little rhizome of the 150 I planted late last October. All the rest had good roots from a neighbor's recent dig. The 150 did well, but did not bloom this year. The wee guy went out in May and I didn't look at it again.
I might pot some rhizomes that arrived with rot and have been severely trimmed. There isn't a bit of green on them as the rot came down from the fan into the rhizomes. They had the daylights bleached out of them and are drying.
